Genesis 20
1 Ref Abraham traveled from there toward the land of the South, and lived between Kadesh and Shur. He lived as a foriegner in Gerar.
2 Ref Abraham said about Sarah his wife, "She is my sister." Abimelech king of Gerar sent, and took Sarah.
3 Ref 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."
4 Ref Now Abimelech had not come near her. He said, "Lord, will you kill even a righteous nation?
5 Ref Didn't he tell me, 'She is my sister?' She, even she herself said, 'He is my brother.' In the integrity of my heart and the innocence of my hands have I done this."
6 Ref God 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.
7 Ref Now 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."
