Genesis 20:2

Abraham traveled from there toward the land of the South, and lived between Kadesh and Shur. He lived as a foreigner in Gerar.

But God came to Abimelech in a dream of the night, and said to him, “Behold, you are a dead man, because of the woman whom you have taken; for she is a man’s wife.”

Now Abimelech had not come near her. He said, “Lord, will you kill even a righteous nation?

Didn’t he tell me, ‘She is my sister’? She, even she herself, said, ‘He is my brother.’ I have done this in the integrity of my heart and the innocence of my hands.”
