Genesis 20:6-7

And God said unto him in a dream, Yes, I know that thou didst this in the integrity of thy heart; for I also withheld thee from sinning against me; therefore I did not allow thee 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. And if thou restore her not, know thou that thou shalt surely die, thou and all that are thine.
