In brief
Lamech is a descendant of Cain, seventh generation from Adam, in the earliest days of humanity told in Genesis 4. He is the first man the Bible says took two wives, Adah and Zillah. His sons stand at the origin of tent-dwelling herdsmen, music and metalworking. He is best known for his song of vengeance: he boasts of having killed a man and claims to be avenged seventy-seven times. He shows how Cain’s sin grows worse from generation to generation.
What does the name Lamech mean?
The meaning of the name Lamech remains uncertain, and the Bible does not explain it. The same name belongs to another man, in the line of Seth, the father of Noah (Genesis 5:25-31), who must not be confused with the descendant of Cain.
The story of Lamech
In Cain’s Line
Genesis 4:16-18After the murder of Abel, Cain leaves Yahweh’s presence and settles in the land of Nod, east of Eden. He builds a city and names it after his son Enoch. The Bible then lists his descendants: Enoch, Irad, Mehujael, Methushael, and finally Lamech. Lamech therefore belongs to a family that moved away from God from its very origin.
Two Wives, Adah and Zillah
Genesis 4:19“Lamech took two wives: the name of the first one was Adah, and the name of the second one was Zillah.” This is the first mention of polygamy in the Bible. The text does not comment on this choice, but it departs from the design described in Genesis 2:24, where a man is joined to his wife and the two become one flesh.
Sons with New Skills
Genesis 4:20-22Adah gives birth to Jabal, father of those who live in tents and keep livestock, then to Jubal, father of all who handle the harp and pipe. Zillah gives birth to Tubal-Cain, who forges every cutting instrument of bronze and iron, and to a daughter, Naamah. Lamech’s family sees the birth of nomadic herding, music and metalworking.
The Song of Vengeance
Genesis 4:23-24Lamech gathers his wives and tells them: “I have slain a man for wounding me, a young man for bruising me.” For a wound he received, he took a life. Then he adds: “If Cain will be avenged seven times, truly Lamech seventy-seven times.” He turns the protection God granted to Cain into a proud claim of personal vengeance.
The Contrast with Seth’s Line
Genesis 4:25-26Right after Lamech’s song, the story returns to Adam and Eve. God gives them Seth in place of Abel, and Seth has a son, Enosh. The chapter ends this way: “At that time men began to call on Yahweh’s name.” On one side, a man who avenges himself; on the other, men who call on God.

- Human talents and progress, such as music or technology, do not replace a living relationship with God.
- Jesus answers Lamech’s logic with limitless forgiveness, far beyond seven times (Matthew 18:21-22).
- God’s design for marriage remains that of Genesis 2:24: one man and one woman united as one flesh.
Key verses
Lamech boasts of having killed over a mere wound and claims a vengeance seventy-seven times greater, where God had only protected Cain. He makes himself judge in his own cause.
When Peter suggests forgiving up to seven times, Jesus answers with a number that goes beyond Lamech’s. Where Lamech wanted vengeance without measure, Jesus asks for forgiveness without measure.
Paul asks believers not to avenge themselves but to leave room for God’s wrath. It is the exact opposite of Lamech, who proclaims his vengeance in front of his wives.

Frequently asked questions
Who was Lamech in the Bible?
The Bible speaks of two men named Lamech. The first, in Genesis 4, is a descendant of Cain: he took two wives, Adah and Zillah, and boasted of having killed a man. The second, in Genesis 5, belongs to the line of Seth; he is the son of Methuselah and the father of Noah, and he died at seven hundred seventy-seven years old.
What does vengeance seventy-seven times mean?
God had declared that if anyone killed Cain, Cain would be avenged sevenfold: it was a protection. Lamech takes up this number to amplify it and turn it into a personal threat. It expresses an excessive vengeance with no limit. Jesus overturns this logic when he asks Peter to forgive far beyond seven times (Matthew 18:22).
Where can I find the story of Lamech in the Bible?
The descendant of Cain appears in Genesis 4:18-24: his genealogy, his two wives, his children Jabal, Jubal, Tubal-Cain and Naamah, then his song of vengeance. The Lamech who fathered Noah, from the line of Seth, is found in Genesis 5:25-31, as well as in the genealogies of 1 Chronicles 1:3 and Luke 3:36.
