Cain and Abel are the first two sons of Adam and Eve in the biblical Book of Genesis. In Hebrew, Cain is called Qayin (קַיִן), and Abel is called Hevel (הֶבֶל). The story of Cain and Abel is found in Genesis 4:1-16 and is a foundational narrative in Judaism, Christianity, and Islam. The tale begins with Cain, a farmer, and Abel, a shepherd, each offering sacrifices to God. God favors Abel's offering over Cain's, leading to Cain's jealousy and ultimately the first murder in human history, as Cain kills his brother Abel. This act results in God's punishment of Cain, who is cursed to a life of wandering. The story explores themes of jealousy, divine favor, and the consequences of sin, serving as a cautionary tale about the dangers of unchecked envy and violence.
