Genesis 4 — Cain, Abel, and the Spread of Sin
Genesis 4 traces the spread of sin from Cain's rejected offering through the first murder, then lists Cain's lineage and Lamech's boast, before turning to Seth as a replacement for Abel.
Scripture
1And the man knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man with the help of Jehovah.
2And again she bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.
3And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto Jehovah.
4And Abel, he also brought of the firstlings of his flock and of the fat thereof. And Jehovah had respect unto Abel and to his offering:
5but unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell.
6And Jehovah said unto Cain, Why art thou wroth? and why is thy countenance fallen?
7If thou doest well, shall it not be lifted up? and if thou doest not well, sin coucheth at the door; and unto thee shall be its desire; but do thou rule over it.
8And Cain told Abel his brother. And it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.
9And Jehovah said unto Cain, Where is Abel thy brother? And he said, I know not: am I my brother's keeper?
10And he said, What hast thou done? the voice of thy brother's blood crieth unto me from the ground.
11And now cursed art thou from the ground, which hath opened its mouth to receive thy brother's blood from thy hand;
12when thou tillest the ground, it shall not henceforth yield unto thee its strength; a fugitive and a wanderer shalt thou be in the earth.
13And Cain said unto Jehovah, My punishment is greater than I can bear.
14Behold, thou hast driven me out this day from the face of the ground; and from thy face shall I be hid; and I shall be a fugitive and a wanderer in the earth; and it will come to pass, that whosoever findeth me will slay me.
15And Jehovah said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And Jehovah appointed a sign for Cain, lest any finding him should smite him.
16And Cain went out from the presence of Jehovah, and dwelt in the land of Nod, on the east of Eden.
17And Cain knew his wife; and she conceived, and bare Enoch: and he builded a city, and called the name of the city, after the name of his son, Enoch.
18And unto Enoch was born Irad: and Irad begat Mehujael; and Mehujael begat Methushael; and Methushael begat Lamech.
19And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah.
20And Adah bare Jabal: he was the father of such as dwell in tents and have cattle.
21And his brother's name was Jubal: he was the father of all such as handle the harp and pipe.
22And Zillah, she also bare Tubal-cain, the forger of every cutting instrument of brass and iron: and the sister of Tubal-cain was Naamah.
23And Lamech said unto his wives: Adah and Zillah, hear my voice; Ye wives of Lamech, hearken unto my speech: For I have slain a man for wounding me, And a young man for bruising me:
24If Cain shall be avenged sevenfold, Truly Lamech seventy and sevenfold.
25And Adam knew his wife again; and she bare a son, and called his name Seth: For, said she, God hath appointed me another seed instead of Abel; for Cain slew him.
26And to Seth, to him also there was born a son; and he called his name Enosh. Then began men to call upon the name of Jehovah.
What this passage means
The chapter opens with two brothers bringing offerings to Jehovah. The text emphasizes the contrast: Abel brought of 'the firstlings of his flock and of the fat thereof,' while Cain brought simply 'of the fruit of the ground.' Jehovah 'had respect unto Abel and to his offering,' but 'unto Cain and to his offering he had not respect.' The chapter never explains the reason within itself; the reader is left to observe the difference in what was brought and how it was presented.
Jehovah confronts Cain before any violence occurs. The question 'If thou doest well, shall it not be lifted up?' implies that Cain still had a choice. The warning that 'sin coucheth at the door' personifies sin as a predator waiting to be let in, and the command 'do thou rule over it' places responsibility on Cain. When the warning is ignored, Cain kills Abel in the field. The dialogue after the murder — 'Where is Abel thy brother?' and 'I know not: am I my brother's keeper?' — establishes accountability before God.
The remainder of the chapter traces two lines. Cain's line ends with Lamech's boast of killing 'a man for wounding me' and escalating vengeance 'seventy and sevenfold.' Then the narrative returns to Adam: Eve names Seth 'For, said she, God hath appointed me another seed instead of Abel.' The chapter closes with the note that 'then began men to call upon the name of Jehovah,' marking a new beginning within the human family.
Context
Genesis 4 follows directly from the expulsion in chapter 3. Adam and Eve, who were driven from the garden, now have children outside it. The chapter moves from Eden to two occupations — shepherding and farming — and shows how sin spreads beyond the original couple. The provided cross references point outward to Hebrews 11:4 (Abel's acceptable sacrifice 'by faith'), James 1:15 (lust conceiving and bringing forth death), and Hebrews 12:24 (the blood of sprinkling that 'speaketh better than that of Abel'), giving later scripture's perspective on what is described here.
Key words in the original
- H3045 Used of Adam 'knowing' Eve (4:1), this verb covers the full range of intimate knowing — here plainly a euphemism for sexual union. The chapter then applies the same word to Cain knowing his wife (4:17), showing that 'knew' in these genealogical contexts is the standard Hebrew idiom for fathering children.
- H2029 The verb behind 'conceived' in 4:1, used twice of Eve within the chapter (4:1, 4:17). It denotes becoming pregnant and frames each conception as a distinct event in the narrative's progression — first Cain, then Abel, later Enoch, and finally Seth.
- H3068 The divine name rendered 'Jehovah' appears repeatedly in chapter 4 — in Cain's birth exclamation (4:1), the offering scene (4:3–5), the curse (4:11–14), and the closing line about calling on 'the name of Jehovah' (4:26). Its recurrence ties the whole chapter under one covenant name.
Related verses
- Hebrews 11:4 This later text identifies the difference between the two offerings as faith: Abel 'offered unto God a more excellent sacrifice than Cain.' Hebrews adds that Abel, though slain, 'being dead yet speaketh,' connecting his blood cry in 4:10 to a continuing witness.
- James 1:15 James traces the same trajectory Genesis 4 displays in narrative form: 'lust, when it hath conceived, beareth sin: and the sin, when it is fullgrown, bringeth forth death.' The link between Cain's unchecked anger, his warning in 4:7, and the murder in 4:8 illustrates this sequence.
- Hebrews 12:24 Hebrews contrasts 'the blood of sprinkling that speaketh better than that of Abel.' Abel's blood 'crieth' from the ground in 4:10; this verse identifies a later sacrifice whose blood speaks a different — a redemptive — message.
Common questions
Why did God accept Abel's offering but reject Cain's?
Genesis 4 does not state the reason within the chapter itself. It only records what each brother brought and that one was accepted and the other was not. Later scripture, such as Hebrews 11:4 in the provided cross references, attributes the difference to faith. The chapter's own emphasis falls on how each approached and what was presented, leaving the reader to weigh the contrast.
What does 'sin coucheth at the door' mean in 4:7?
The Hebrew figure pictures sin as a crouching predator waiting at the entrance. The verse pairs this image with the command 'do thou rule over it,' indicating that the danger is real but not yet decisive. Cain is being warned before the act, not condemned after it. The option 'if thou doest well, shall it not be lifted up?' frames the moment as a still-open choice.
Where did Cain's wife come from in 4:17?
The chapter does not explain her origin. Genesis 4 presupposes a wider human population descended from Adam and Eve beyond the named individuals of the genealogy. The text names Cain, Abel, and Seth, but the narrative assumes other sons and daughters existed; 4:17 simply records the next event without addressing the source of the wife. The chapter itself does not discuss the question.
