Genesis 20:6; Genesis 20:7

6 Then God said to him in the dream, "Yes, I know that you have done this in the integrity of your heart, and it was I who kept you from sinning against me. Therefore I did not let you touch her.

7 Now then, return the man's wife, for he is a prophet, so that he will pray for you, and you shall live. But if you do not return her, know that you shall surely die, you and all who are yours."
