Cain and Abel: God's Judgment, Mercy, and Our Responsibility
This post is part 3 of my Investigating Judgment series and focuses on Genesis 4 and the story of Cain and Abel.
My Brother’s Keeper: What Cain and Abel Reveal About God’s Judgment
God's mercy does not require Him to deny wrongdoing, and His justice does not require Him to abandon mercy.
The First Birth
4 Now Adam knew Eve his wife, and she conceived and bore Cain, and said, “I have acquired a man from the Lord.”
—Genesis 4:1 NKJV
Of course, there is debate over verse one and how best to translate it. For example, the New American Commentary argues that Eve’s comment on the child's birth reflects her renewed dependence on the Lord. It also argues that the birth of her first son rekindled her faith in the goodness of God and the veracity of His promise in Genesis 3:15. Luther (and others) read it differently by reading the Hebrew “a man of the Lord” as though Cain were the savior foreseen in Genesis 3:15. I will not chase this topic further here (see footnotes), but suffice it to say that the grammar in Genesis 4:1 allows for the possibility that Eve expected Cain to be the Messiah who would crush the head of the serpent.
Genesis 4 begins full of hope. There is new life, the miracle of birth, and the hope of salvation.
Another Baby!
Then she bore again, this time his brother Abel. Now Abel was a keeper of sheep, but Cain was a tiller of the ground.
—Genesis 4:2 NKJV
Abel is introduced as Cain’s brother, establishing that the story will focus on Cain. Cain is mentioned 13 times in Genesis 4:1–16, while Abel is mentioned seven times, and “brother” is substituted three other times. Zero words of Abel are recorded in the biblical text, making him seem almost absent from this story.
We also learn that Abel kept sheep and Cain tilled the ground. This detail is important as the story progresses. I also find it interesting that this detail connects Cain to the ground, which was cursed in Genesis 3:17. While Abel is connected to sheep, this might be a bit of a stretch, but I see a connection with the tunics of skin God made for Adam and Eve. The text does not say the clothing was made from sheepskin, but more generally, Cain is connected to plants; think fig leaves (Genesis 3:7), while Abel is connected to livestock and tunics of skin.
Worship Wars
3 And in the process of time it came to pass that Cain brought an offering of the fruit of the ground to the Lord. 4 Abel also brought of the firstborn of his flock and of their fat. And the Lord respected Abel and his offering, 5 but He did not respect Cain and his offering. And Cain was very angry, and his countenance fell.
—Genesis 4:3-5 NKJV
Who expected the first act of worship or religious expression ever recorded in the Bible, an offering to God, to become the catalyst for the first murder? To complicate matters further, the biblical text in Genesis 4 never gives a clear reason why God rejects Cain’s offering, and as a result, there is much debate on possible reasons.
Some argue that the absence of a clear rationale on God’s part is evidence that divine election is a mystery and should be viewed as capricious (at least from our human perspective) and as fated by God to be so. I do not find compelling support for this view in light of the larger biblical narrative. It is also worth noting that Cain was not condemned from the beginning. His offering was rejected, but there is nothing said against Cain personally.
Another argument is that the gift came from the ground that was cursed, but God directed Adam to work the ground and eat from what it produces. Because of the curse, this work would be more difficult, but the work itself is not cursed. The curse caused plants to have thorns and thistles, but the fruit of the ground was not considered cursed.
The reason for the rejection then must be something more nuanced, and we will explore that together.
Diving Deeper
From the text (Gen. 4:3), there is no mention that Cain brought the firstfruits (Lev. 2:14), but simply an offering of the fruit of the ground. This would be a small detail, but when we read the account of Abel’s offering, we notice that he brought not only “some” of his flock but the “firstborn,” and not just some of the firstborn of his flock but the best of the animal, the fatty portions (v. 4). The firstborn or firstfruits may seem like a small detail to modern readers, but this is significant. Later Israel acknowledged the efficacy of both grain and blood offerings, but, of these, the firstfruits (Exod. 23:16) and firstborn (Exod. 13:2, 15; Lev. 27:26; Deut. 15:19) were reserved for God.
Israel itself was regarded as God’s firstfruit (Jer 2:3) and firstborn (Exod 4:22). This imagery shared by the church (e.g., Rom 11:16; Heb 12:23) and Christ (e.g., Rom 8:29; 1 Cor 15:20, 23) as the “firstborn” indicates the blessing of God and the veneration of the Lord by his people.
—K. A. Mathews, Genesis 1-11:26, vol. 1A, The New American Commentary (Nashville: Broadman & Holman Publishers, 1996), 267–268.
The Heart of the Giver
When we read Genesis 4:4-5 carefully, we notice that the LORD regarded Abel and his offering but did not regard Cain and his offering. The issue was not just the quality of the gift but also the condition of the giver's heart. You could argue that Cain’s offering did not measure up because of the posture of his heart. As humans, we see only the gift, but God sees the condition of the giver's heart and knows the worshiper's motive. ( See 1 Samuel 16:7)
When another Bible passage references a story, it helps us interpret it more accurately; for example, Hebrews 11:4 says, “By faith Abel offered to God a more excellent sacrifice than Cain.” God is concerned not merely with what we bring Him, but with the faith and devotion expressed through our offering (see Isaiah 1:11; Micah 6:7).
In the narrative, Cain’s offering precedes Abel’s, but God’s acceptance of Abel’s offering precedes His rejection of Cain’s. I love how God’s act of love precedes His act of justice.
Cain’s Anger
Cain is very angry; the same word is used to describe Jonah (Jonah 4:9), where he says he is angry enough to die. The text also describes that Cain’s countenance fell. This is a unique phrase that occurs only here. There is some debate about whether Cain was experiencing anger or depression, but this seems to be a modern distinction that the biblical text does not clarify.
Investigation
So the Lord said to Cain, “Why are you angry? And why has your countenance fallen?
— Genesis 4:6 NKJV
I call this an investigation because of the theme of this series, and I mean that God showed up and asked questions. This is what God did for Adam and Eve (Genesis 3:9, 11, 13) (see The First Judgment: What Genesis 3 Reveals About God's Character). God’s first question guides Cain to reflect and become aware of his sin. You might argue that Cain has not yet sinned since he has not taken any actions. But God’s concern is in line with what Jesus taught in the Sermon on the Mount (see Matthew 5:21-24, It Begins in the Heart). God wants to deal with our hatred long before we act on it. When we feel the anger burning in us, that is the time to bring it to God. God speaks to Cain not because He doesn't know what is going on in his heart, but because He wants to help Cain deal with the issue now, before anything worse happens.
In Genesis 4:6, we see another clear example of God investigating not to gain new information, but to give the sinner an opportunity to come to Him and receive help. The investigation is not because God is looking for evidence to condemn someone; rather, God seeks to connect with the sinner to save them. God is not scolding Cain; He is trying to save him. If Cain recognizes his sin and repents, a tragedy can be prevented.
The most obscure verse in the book of Genesis
If you do well, will you not be accepted? And if you do not do well, sin lies at the door. And its desire is for you, but you should rule over it.”
— Genesis 4:7 NKJV
This verse presents translators with a number of problems, so much so that Jewish tradition counted it as one of the indeterminate verses (b. Yoma 52a-b), and some modern commentators have given up on discovering its meaning (Mathews, 269). One solution to this challenge is to appeal to other biblical passages that may be similar, and in this train of thought we can look to Isaiah 1:17, where the prophet tells the people of Israel to learn to do good, to seek justice, rebuke the oppressor, defend the fatherless, and plead for the widow, and assume that God is doing something similar here, telling Cain to do good.
One way to interpret Genesis 4:7 is that God is telling Cain to do the right thing, and to be accepted, or to have his downcast countenance lifted up. What we know for sure is that Cain refused to do right, and his anger festered into murder. John makes this clear in his first epistle.
10 In this the children of God and the children of the devil are manifest: Whoever does not practice righteousness is not of God, nor is he who does not love his brother. 11 For this is the message that you heard from the beginning, that we should love one another, 12 not as Cain who was of the wicked one and murdered his brother. And why did he murder him? Because his works were evil and his brother’s righteous.
13 Do not marvel, my brethren, if the world hates you. 14 We know that we have passed from death to life, because we love the brethren. He who does not love his brother abides in death. 15 Whoever hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.
— 1 John 3:10-15 NKJV
This principle appears throughout the Bible (Prov. 27:4; Eccl. 7:9; Eph. 4:26, 31; Jas. 1:15). Despite the challenges of translating this passage, some things are clear. Cain did not have to continue on the path of anger and hatred. God reached out to him personally, warning him and pointing him in the right direction. Cain had a choice, and God even told him the best option.
The First Murder
Now Cain talked with Abel his brother; and it came to pass, when they were in the field, that Cain rose up against Abel his brother and killed him.
—Genesis 4:8 NKJV
Cain did not murder Abel by mistake. Cain was not just messing around. This sin was premeditated and committed after God talked personally to Cain. Have you ever told someone to do something, only for them to completely disregard what you said? How did it make you feel? I was reflecting on that as I read this story. If I were God, I would have been furious at Cain. Apparently, Cain planned this whole thing, and many translations have Cain inviting Abel to the field in order to kill him. This reminds us of some of the crimes that were punishable by death in Israel (Deut. 19:11; 22:25-27). There is no question about Cain’s guilt in Abel's death. This was cold-blooded murder. How will God react to this? What will God do?
Investigation
9 Then the Lord said to Cain, “Where is Abel your brother?”
He said, “I do not know. Am I my brother’s keeper?”
10 And He said, “What have you done? The voice of your brother’s blood cries out to Me from the ground.
— Genesis 4:9-10 NKJV
Maybe some of you are upset that God knew that Cain was angry and yet He did not stop Cain from murdering his younger brother. God came and talked to Cain. Cain had the opportunity to ask questions, to ask for help. If Cain did not know or understand why his offering was rejected, he could have asked God. It seems Cain’s problem was not ignorance but rebellion. Cain chose murder instead of obedience. Cain did not make this choice because he was ignorant of God or His will. Cain was aware of both.
This is obvious, but I want to point it out nonetheless. Cain was not trying to do right but messed up. Cain was not trying to obey God but fell short. Cain did not make an honest mistake with the best of intentions. Cain planned and followed through. Cain had a personal conversation with God and decided to murder Abel, his younger brother. Now he faces investigation and judgment, much like his parents in Genesis 3.
God initiates another conversation with Cain. Once again, God asks a question, not because He needs information, but to prompt Cain to reflect on his sin. When God asks him where his brother Abel is, Cain lies to God and talks back like a petulant child.
“Am I my brother’s keeper?”
I am amazed by God’s self-control. I believe a human being would have felt an overwhelming urge to introduce the back of their hand to Cain’s face. But God asks another question: “What have you done?” Here is another opportunity for Cain to confess, to come clean, to repent, to turn to God for forgiveness and restoration. God knows what happened and lets Cain know that the blood of his brother cries out to God from the ground. The injustices and the violence that take place in this world do not go unnoticed by God in heaven. God must respond to the pain caused to the innocent.
Adam and Eve shifted the blame when God questioned them, but they did not lie. Cain lies to God and adds a question about his responsibility for his brother. God makes this responsibility abundantly clear both in the Old and New Testaments.
You shall not take vengeance, nor bear any grudge against the children of your people, but you shall love your neighbor as yourself: I am the Lord.
— Leviticus 19:18 NKJVFor all the law is fulfilled in one word, even in this: “You shall love your neighbor as yourself.”
— Galatians 5:14 NKJV
Mutual responsibility is foundational for a healthy community.
Good vs Evil
It is easy to consider the battle of good vs. evil as a spiritual battle involving angels, demons, and spiritual powers. However, God describes it as the seed of the woman against the seed of the serpent. The enmity between good and evil predicted by God in Genesis 3:15 is playing out in front of us in this story. Cain, the firstborn of Eve, could have been a step in the direction of the seed of the woman triumphing over the serpent. However, what we have is the seed of the woman becoming the seed of the serpent. This did not happen by accident. Cain did not become evil while trying to do the right thing. Cain disregarded God’s words to him, killed his brother, and now lied to God about it. Does Cain really think God doesn't know what happened?
Abel met his death at the hand of his brother. Similarly, Jesus came to earth as a brother to the human race; His brothers rejected Him and killed Him.
Judgment
God reached out to Cain while he was angry. Before he acted on his anger. God reasoned with Cain and pointed the right path to him. Cain rejected God. Cain planned and murdered his brother in cold blood. God confronted Cain again; Cain lied to God. Cain shows no signs of repentance in this story. What is God going to do?
11 So now you are cursed from the earth, which has opened its mouth to receive your brother’s blood from your hand. 12 When you till the ground, it shall no longer yield its strength to you. A fugitive and a vagabond you shall be on the earth.”
—Genesis 4:11-12 NKJV
Cain is the first person to be cursed by God. In Genesis 3, we witness God cursing the serpent and the ground, and now Cain is cursed. Now there is an added separation between Cain and the earth. All humans struggle with weeds and thistles and getting food from the soil. It takes work to grow a vegetable garden. But though the work is difficult, it can be rewarding in many ways. Cain, however, will have an especially difficult time making things grow. The wording of the curse clarifies that this is because the ground drank the innocent blood of Abel. Not only that, Cain will be a fugitive and a vagabond.
Since Cain does not see himself as his brother’s keeper, he will not experience community. His lack of compassion and care for his brother are now a curse on his life and all his future relationships. The evil Cain chose to embrace will now make the rest of his life miserable.
Cain’s Response
Suddenly, Cain wants to talk.
13 And Cain said to the Lord, “My punishment is greater than I can bear! 14 Surely You have driven me out this day from the face of the ground; I shall be hidden from Your face; I shall be a fugitive and a vagabond on the earth, and it will happen that anyone who finds me will kill me.”
— Genesis 4:13-14 NKJV
Cain finally takes the opportunity to have a conversation with God, and from his words we gain insights into his heart. There is no evidence in this story that Cain repents for murdering his brother. There are no signs of remorse in his speech. Cain’s words do not express regret for murdering his brother. Cain does not ask for forgiveness, express a desire to change, or invite God to help him; he does not turn to God seeking a new life or a better way forward. Cain complains that the judgment is too harsh and that someone will kill him.
Cain is concerned about himself and his lifespan. Cain is concerned that others will be like him and plot his murder. He will have to sleep with one eye open, always suspicious of everyone around him, always careful about where he goes. Maybe Cain considered Abel too trusting, too innocent, too naive. But now Cain feels paranoid; he fears that anyone who finds him will want to kill him. He doesn’t want to live in a reality where he can’t trust others to not do to him what he did to his brother. How ironic, isn’t it?
How will God react? Maybe God will explain to Cain how He warned him not to go down this path. Maybe God will tell Cain that he should have thought about this before he murdered his own brother in cold blood. Maybe God will tell Cain that he made his bed and now he has to lie in it. Something along the lines of: this is the path he chose. Maybe God will have a long conversation with Cain about choices and consequences. For example, if you don’t like the idea of being murdered by someone, maybe try not murdering anyone, especially your own brother.
But that is not what God does.
God’s Mercy
And the Lord said to him, “Therefore, whoever kills Cain, vengeance shall be taken on him sevenfold.” And the Lord set a mark on Cain, lest anyone finding him should kill him.
— Genesis 4:15 NKJV
This next part blows my mind. God is merciful to an unrepentant man who murdered his brother in cold blood. God did not have to listen to Cain. God could have killed him right then and there, but instead God set a mark on Cain so that he would not be murdered by another person. God allows Cain to live out the rest of his life here on earth. I see this as further evidence that God is not looking for opportunities to condemn anyone, but to restore and save. God takes the suffering of the innocent seriously while still showing restraint toward the guilty.
God’s mercy toward Cain does not mean that Abel’s death is ignored. God hears the blood crying out from the ground and holds Cain accountable for what he has done. The same God who warns Cain before the murder confronts him after it. Divine mercy does not erase justice, and divine justice does not eliminate mercy.
We are never told if Cain ever repented or changed his ways. We do not know how long he lived on earth. We are told in Genesis 4:16-24 that from the descendants of Cain we have the first biblical example of polygamy (verse 19) and that his descendant Lamech was proud of how violent he was, even composing a song describing his violence and how he was even more violent than Cain.
A New Son
Lest the story end on a negative note, we are told that Adam and Eve had another son; this one they named Seth. Interestingly, Seth is called another seed for Eve instead of Abel, whom Cain killed. In the lineage of Seth, we have Enosh, and a new distinction arises: those who worship God and those who defy Him. From Seth, the seed of hope is preserved, and by calling on the name of the LORD, a message of salvation is preserved and proclaimed.
Takeaway
As far as judgment and investigation are concerned, we see a continuation of the pattern we noticed in Genesis 3 (The First Judgment: What Genesis 3 Reveals About God's Character). God shows up and “investigates,” asking questions not because He lacks information, but to prompt the sinner to reflect on their choices. What is unique about this story is that God shows up when Cain is angry, before he commits murder, and this is in line with Jesus’ words in Matthew 5:21-24 about hate.
Even though Cain never shows any signs of repentance or desire to change in this story, God does not kill him, and even gives him a mark to keep anyone else from killing him. God’s protection of the guilty murderer from being killed by someone else demonstrates that divine judgment is not just an impulse to destroy the guilty.
In Genesis 3:15, God puts enmity between the seed of the serpent and of the woman. Genesis 4 ends with two groups of people: the descendants of Cain, a lineage that includes Lamech, who was polygamous and boasted of violence. And the descendants of Seth, the new seed instead of Abel, who begin to establish corporate worship of God. Humanity is divided into two groups. Those who call on the name of the LORD, and those who reject God.
Practical Application
Cain did not see himself as his brother’s keeper. This led to hate and eventually murder. Cain was cursed and banished but not killed. His disregard for God’s will led to murder, and his lineage later included Lamech, whose polygamy and boast of violence illustrate the further development of sin and evil.
The challenge with seeing ourselves as our brother’s keeper is that it means taking responsibility for others. That mental load of concern for someone else's well-being is not a bug but a feature of community. We don’t get to live selfish lives if we want to experience community. This is part of the reason why, even though salvation is a private matter, we form and join churches. The life of the follower of God is lived in community and with regard for the well-being of those around us.
This is not a light load to carry. So we do it together. This also must be kept in balance, or the weight of responsibility can crush us. But not caring about anyone else is not an option for the follower of God.
Take a moment and text three people whom you have not seen or heard from in a while. Check in and see how they are doing. What is one thing you can do this week to help someone who is struggling, who was wronged, or who is being overlooked?
This does not have to cost money, but it will take time and effort. This is a worthwhile effort.
Footnotes:
The first birth
Of course, there is debate over verse one and how best to translate it. For example, the New American Commentary argues that Eve’s comment on the child's birth reflects her renewed dependence on the Lord. It also argues that the birth of her first son rekindled her faith in the goodness of God and the veracity of His promise in Genesis 3:15. I appreciate their recognition that not everyone accepts this view. Luther (and others) read it differently. The New American Commentary argues that Luther and those with similar views attribute too much to Eve by reading the Hebrew “a man of the Lord” as though Cain were the savior foreseen in Genesis 3:15. ( K. A. Mathews, Genesis 1-11:26, vol. 1A, The New American Commentary (Nashville: Broadman & Holman Publishers, 1996), 265.) I will not chase this topic further, but suffice it to say that the grammar in Genesis 4:1 allows for the possibility that Eve expected Cain to be the Messiah who would crush the head of the serpent.
Reflections on the offerings of Cain and Abel.
The original Hebrew word used for Cain’s “offering” as well as Abel’s is described with the same term minḥâ, which can be used as a general reference to any kind of “gift,” such as that given among brothers (Gen. 32:13) or to a king (1 Sam. 10:27), or it can be a technical term for the “cereal” offering presented to the Lord (see Lev. 2:1–7; 6:12–14; Num. 15:1–16) (Mathews, 267). So the word itself does not give us many clues, except to clarify that this was not a sin offering. Though this same word is used in 1 Samuel 2:17 as a reference to an animal offering. The unusual element in the story regarding the use of minḥâ is not that Cain’s offering is bloodless but that Abel’s is bloody. (See B. K. Waltke, “Cain and His Offering”, Westminster Theological Journal 48 (1986) p. 366). Because this passage does not have any reference to the general Hebrew word used for sacrifice or any reference to sin, burnt, guilt, or peace offerings, it is difficult for the reader to know what kind of offering this was.
When we consider Genesis 4 in light of Genesis 3, we notice that Cain’s offering of the fruit of the ground to the LORD is reminiscent of Genesis 3:7, when Adam and Eve sewed fig leaves together and made for themselves coverings. The mention of the ground also reminds us of the curse mentioned in Genesis 3:17. Perhaps Cain sees religion as an upward movement towards God. Abel, on the other hand, experiences religion as a response to God’s downward movement towards us. His offering is not only of the firstborn and the best, but it also reminds us of what God did for Adam and Eve when He made tunics of skin and clothed them (Genesis 3:21). One way of looking at the offering of Cain and Abel, along with everything else I have mentioned in this post so far, is that Cain’s offering reminds us of those who want to use religion as an effort towards God, and Abel’s offering reminds us of those who understand our need for God’s salvation. Perhaps this is how Abel's faith (Heb. 11:4) is revealed.
Sin crouching at the door.
Here we come to another interpretive obstacle in the verse, how to understand sin as “crouching” and what is meant by “door.” “Sin” is likened to an animal “crouching” or “lurking” (NRSV) at the “door,” meaning the animal’s resting place, ready to stir if incited. “Crouch” (rābaṣ) is commonly used of domesticated animals in repose (i.e., 29:2; 49:9; Exod 23:5), including wild animals such as the lion (Gen 49:9). This pictures sin temporarily at bay and subject to its master but coming alive when stirred. Some commentators have compared the Hebrew rōbēṣ (“crouch”) to the cognate Akkadian term rābiṣum, a mythological demon attending the doorways of buildings to guard its inhabitants or conversely to threaten them. The REB thus reads, “Sin is a demon crouching at the door.” If there is an allusion to the door demon, then the narrative is personifying sin as a demonic spirit ready to pounce on Cain once he opens the “door” of opportunity. This may well correspond with the “seed” of the serpent in 3:15, which will do battle with the “seed” of the woman Eve. The imagery is effectively the same and the message clear: sin can be stirred up by wrong choices.
Complicating this is a grammatical incongruity: where Hebrew customarily has gender correspondence, “sin” (חַטָּאת, feminine) disagrees with “crouching” (רֹבֵץ, masculine) as well as the masculine pronouns “its desire” (תְּשׁוּקָתוֹ) and “in it” (בּוֹ). Since it is a predicate, we would expect the feminine form of the participle since its subject “sin” is feminine. A common emendation is based on a haplography of ת, thus לַפֶּתַח חַטָּאת תִרְבַּץ, “sin lies at the door.” Without emendation perhaps רֹבֵץ is a substantive, meaning “lurker, croucher” (GKC § 145u): “Sin is a lurker at the door.” (Mathews, 1996).
Another way of looking at this is to interpret “sin” (חַטָּאָת ḥaṭṭā'āṯ) as sin offering (Leviticus 4:25; Exodus 29:14), making this a reference to the atoning sin offering, that is, the sacrificial animal. This view has support among some, but also has its challenges.
