Cain and Abel ( Qayin, Heḇel; Qabeel, Habeel) 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 Abel was the first human to die. Cain committed the first murder by killing Abel. Interpretations of Genesis 4 by ancient and modern commentators have typically assumed that the motives were jealousy and anger. The story of Cain and Abel is found in the Christian Bible, Jewish Torah and Muslim Quran.
