Genesis 20:6-7

And God said to him: And I know that thou didst it with a sincere heart: and therefore I withheld thee from sinning against me, and I suffered thee not to touch her. Now therefore restore the man his wife; for he is a prophet. And he shall pray for thee, and thou shalt live: but if thou wilt not restore her, know that thou shalt surely die, thou and all that are thine.
