And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him.

“Not so!” replied the LORD. “If anyone slays Cain, then Cain will be avenged sevenfold.” And the LORD placed a mark on Cain, so that no one who found him would kill him.

If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold.

If Cain is avenged sevenfold, then Lamech seventy-sevenfold.”
