Cain and Abel were, according to the Book of Genesis, two sons of Adam and Eve. Cain is described as a crop farmer and his younger brother Abel as a shepherd. Cain was the first human born and the first murderer, and Abel was the first human to die. Cain committed the first murder by killing his brother. No motive is given in the Genesis narrative for the murder. Exegesis of Genesis 4 by both ancient and modern commentators have typically assumed that the motive was driven by jealousy.
