Summary
After Adam and Eve's first children, Cain and Abel, present offerings to the Lord; God favors Abel’s offering over Cain’s, igniting Cain’s jealousy. God confronts Cain, warning him that sin is at the door, yet Cain murders Abel. The Lord questions Cain, condemns him with a curse and a protective mark, and declares that anyone who kills Cain will suffer sevenfold vengeance. Cain flees to the land of Nod, marries, and founds a city named after his son Enoch. The narrative continues with a brief genealogy from Cain to Lamech, and then introduces Seth, the descendant of Adam who replaces Abel, indicating a line of righteousness. The chapter concludes with the naming of Enos, marking the beginning of people calling upon the name of the Lord.
