Cain

Life and work

Cain was the firstborn son of Adam and Eve; Genesis identifies him as 'a worker of the ground,' in contrast to his younger brother Abel, who kept flocks (Genesis 4:1-2).

Both brothers brought offerings to the LORD — Cain from the fruit of the ground, Abel from the firstborn of his flock. God regarded Abel's offering favorably but had no regard for Cain's, and Cain became very angry, his face falling. God warned him that sin was 'crouching at the door,' desiring to have him, but that he must rule over it (Genesis 4:3-7).

Cain lured Abel into a field and killed him. When God asked where his brother was, Cain answered, 'I do not know; am I my brother's keeper?' God declared that Abel's blood cried out from the ground, and cursed Cain: the ground would no longer yield its strength to him, and he would become a restless wanderer (Genesis 4:8-12).

Cain protested that his punishment was too great to bear and that anyone who found him might kill him. God responded by putting a mark on Cain so that no one who found him would kill him, and Cain went out from the LORD's presence to settle in the land of Nod, east of Eden, where he built a city and named it after his son Enoch (Genesis 4:13-17).

The genealogy that follows traces Cain's line through several generations to Lamech, who took two wives and boasted of killing a man in self-defense, escalating the violence introduced by his ancestor (Genesis 4:18-24).

Questions and debates

The 'mark of Cain' (Genesis 4:15) was, in later centuries, badly misread and misused by some interpreters — particularly in early modern America — to claim that Cain's mark was dark skin and that his curse justified the enslavement or subjugation of Black people. The text itself specifies only that the mark was protective, not punitive or racial, and mainstream biblical scholarship rejects this later interpretive tradition entirely.

Extra-biblical evidence

No extra-biblical inscription or ancient record refers to Cain as a historical figure; he is known only from the Genesis narrative and its reception history.

Reflect

God warned Cain that sin was crouching at his door, but that he could master it — what is crouching at yours?
