Sevenfold vengeance shall be taken for Cain: but for Lamech seventy times sevenfold.
Jesus saith to him: I say not to thee, till seven times; but till seventy times seven times.
And the Lord said to him: No, it shall not be so: but whosoever shall kill Cain, shall be punished sevenfold. And the Lord set a mark upon Cain; that whosoever found him should not kill him.
