This biblical text details the story of Cain and Abel, the first sons of Adam and Eve. It describes how God favored Abel's offering over Cain's, leading to Cain's jealous murder of his brother. Cain is then cursed and driven from the land, though God places a mark upon him for protection. The passage also briefly traces Cain's descendants and introduces Seth, another son of Adam and Eve. The narrative highlights early human history and the consequences of sin.
