Cain (kâin), possession. Genesis 4:1. The eldest son of Adam and Eve; he tilled the ground as a farmer. In a fit of jealousy, roused by the rejection of his own sacrifice and the acceptance of Abel's, he slew his brother, and became an exile from God's presence, but received a promise of protection from the avenger of blood. He settled in the land of Nod, and built a city, which he named after his son Enoch. His descendants are enumerated, together with the inventions for which they were remarkable. 2. A city, called "Kain" in R. V., in the mountains of Judah. Joshua 15:57.
