Genesis 20:5-8

5Did he not himself say to me, 'She is my sister'? And she herself said, 'He is my brother.' In the integrity of my heart and the innocence of my hands I have done this."

6Then 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.

7Now 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."

8So Abimelech rose early in the morning and called all his servants and told them all these things. And the men were very much afraid.
