'Seven fold' in the Bible

And Jehovah will say to him, Therefore, every one killing Cain, he shall be avenged seven fold. And Jehovah will put a sign upon Cain, lest any finding him, smite him.

If Cain shall be avenged seven fold, also Lamech seventy and seven.

And turn back to our neighbors seven fold to their bosom their reproach which they reproached thee, O Jehovah.

And being found he shall recompense seven fold; he shall give all the substance of his house.

And the light of the moon was as the light of the sun, and the light of the sun, shall be seven fold, as the light of seven days, in the day Jehovah bound up the breaking of his people, and he will heal the wound of his smiting.
