From the time sin entered God’s world, things have gone from bad to worse. Disobedience to God’s commands has led to betrayal, conflict, jealousy, even murder. The human race has lost the privileges of the garden of Eden, and now Cain has lost what little was available to him, having been sent out “from the Lord’s presence” (Genesis 4:16).

Thanks to God’s grace in protecting Cain, possibly from a revenge killing (v. 15), he is able to survive and rebuild his life. He does well, building a city and forging a reputation with his own family line (vv. 17–22). But the author of Genesis wants to remind us about the spread of sin through the generations. So he takes us down to Lamech, the seventh generation from Adam through Cain, whose brief account typifies the odd mixture of glory and shame that has marked human society ever since (vv. 19–24).

On one hand, Lamech is the father of remarkable human advancement in the areas of animal husbandry, the arts, and technology, with his three sons being distinguished by specific achievements.

Jabal sets the pace for the raising of livestock that would supply food and clothing to a growing population (v. 20). Jubal represents the development of the arts, in this case musicians playing “stringed instruments and pipes” (v. 21). Tubal-Cain is credited with the development of technology (v. 22). The earliest humans used stone implements, but the transition from the Stone Age to the use of bronze and iron was a stunning technological advancement. Lamech’s third son paves the way for societies to flourish in this manner.

The account also mentions a daughter (v. 22), whose name, Naamah, means “pleasant, graceful, gorgeous”.¹ Perhaps the author is trying to complete the picture he has painted of a family (and society) that shows the great potential God placed in humanity.

Nevertheless, Lamech has a dark side. He marries two women and thus violates God’s blueprint for marriage (v. 19, see 2:24). He does not restrain his own tendency to violence (4:23) and he is arrogant (v. 24). When provoked, he did not hesitate to kill a youth or a child, and he boasts that he would be avenged “seventy-seven times”, an expression of his self-importance.

Just when all seems lost, however, God intervenes again. Adam fathers a son “in place of Abel”, who Eve says is God’s gift of “another child” (v. 25; see 3:15). Seth will start a parallel line of children descended from Adam, which restores hope in the biblical story: “At that time people began to call on the name of the Lord” (4:26).
