Genesis 20:3-5

3One night, however, God came to Abimelech in a dream and told him, “You are as good as dead because of the woman you have taken, for she is a married woman.”

4Now Abimelech had not gone near her, so he replied, “Lord, would You destroy a nation even though it is innocent? 5Didn’t Abraham tell me, ‘She is my sister’? And she herself said, ‘He is my brother.’ I have done this in the integrity of my heart and the innocence of my hands.”
