Genesis 20:3

1Abraham traveled from there toward the land of the South, and lived between Kadesh and Shur. He lived as a foreigner in Gerar.

2Abraham said about Sarah his wife, “She is my sister.” Abimelech king of Gerar sent, and took Sarah.

3But 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.”

4Now Abimelech had not come near her. He said, “Lord, will you kill even a righteous nation?

5Didn’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.”

6God said to him in the dream, “Yes, I know that in the integrity of your heart you have done this, and I also withheld you from sinning against me. Therefore I didn’t allow you to touch her.

7Now therefore, restore the man’s wife. For he is a prophet, and he will pray for you, and you will live. If you don’t restore her, know for sure that you will die, you, and all who are yours.”
