According to Genesis, Adam and Eve’s first son was named Cain. Genesis presents Cain as the couple’s first child after their expulsion from Eden, followed by his brother Abel.
Cain worked as a farmer, while Abel kept sheep. Their offerings to God are described differently, and Cain became angry when Abel’s offering found greater favor. Cain then killed Abel in the first recorded murder in the biblical narrative.
Afterward, God questioned Cain, who replied with the famous question, “Am I my brother’s keeper?” Cain was condemned to a life of wandering, though God also placed a protective mark on him. The name Cain is sometimes confused with Abel, the younger brother, or Seth, another son born later to Adam and Eve.
Genesis later connects Cain’s family line with figures such as Enoch, but this Enoch is distinct from the ancestor of Noah in the separate genealogy of Seth.
