Cain is a biblical figure in the Book of Genesis within Abrahamic religions. He is the elder brother of Abel, and the firstborn son of Adam and Eve, the first couple within the Bible. He was a farmer who gave an offering of his crops to God. However, God was not pleased and favored Abel's offering over Cain's. Out of jealousy, Cain killed his brother, for which he was punished by God with the curse and mark of Cain. He had several children, starting with Enoch and including Lamech.

Abel is a Biblical figure in the Book of Genesis within Abrahamic religions. He was a younger brother of Cain, and the second son of Adam and Eve, the first couple in Biblical history. He was a shepherd who offered his firstborn flock up to God as an offering. God accepted his offering but not his brother's. Cain then killed Abel out of jealousy.
