Genesis 20:3-5

31But God came to Abimelech in a dream of the night, and said to him, “Behold, 2you are a dead man because of the woman whom you have taken, for she is 3married.”

4Now Abimelech had not come near her; and he said, “Lord, 4will You kill a nation, even though 5blameless?

5Did he himself not say to me, ‘She is my sister’? And she 6herself said, ‘He is my brother.’ In 7the integrity of my heart and the innocence of my 8hands I have done this.”
