The Bible
Genesis 4
Eve bears Cain and Abel—They offer sacrifices—Cain slays Abel and is cursed by the Lord, who also sets a mark upon him—The children of men multiply—Adam begets Seth, and Seth begets Enos.
6And the Lord said unto Cain, Why art thou wroth? and why is thy countenance fallen?
10And he said, What hast thou done? the voice of thy brother’s blood crieth unto me from the ground.
13And Cain said unto the Lord, My punishment is greater than I can bear.
20And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle.
21And his brother’s name was Jubal: he was the father of all such as handle the harp and organ.
24If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold.
