Genesis 20:3-5

3But God came to Abimelech in a dream by night and said to him, “You are about to die because of the woman you have taken, for she is a married woman.”

4Now Abimelech had not approached her, so he said, “Lord, would you destroy a nation even though it is innocent?

5Didn’t he himself say to me, ‘She is my sister’? And she herself said, ‘He is my brother.’ I did this with a clear conscience and clean hands.”
