'Seven fold' in the Bible

And the LORD said unto him, "Not so, but whosoever slayeth Cain shall be punished sevenfold." And the LORD put a mark upon Cain that no man that found him should kill him.

For Cain shall be avenged sevenfold: but Lamech seventy times sevenfold."

And for the blasphemy wherewith our neighbours have blasphemed thee, reward them, O LORD, seven fold into their bosom.

the moon shall shine as the sun, and the sunshine shall be seven fold, and have as much shine, as in seven days beside. In that day shall the LORD bind up the bruised sores of his people, and heal their wounds.
