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.

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

And render unto our neighbours sevenfold into their bosom their reproach, wherewith they have reproached thee, O Lord.

But if he be found, he shall restore sevenfold; he shall give all the substance of his house.

Moreover the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days, in the day that the LORD bindeth up the breach of his people, and healeth the stroke of their wound.
