Genesis 20:1-7

Abraham traveled from there south to the Negev and settled down between Kadesh and Shur. While he was camping in Gerar, Abraham said of his wife Sarah, “She’s my sister.” So Abimelech, king of Gerar, sent for Sarah and took her. But God came to Abimelech in a dream that night and told him, “You’re as good as dead—that woman you took, she’s a married woman.” Now Abimelech had not yet slept with her, hadn’t so much as touched her. He said, “Master, would you kill an innocent man? Didn’t he tell me, ‘She’s my sister’? And didn’t she herself say, ‘He’s my brother’? I had no idea I was doing anything wrong when I did this.” God said to him in the dream, “Yes, I know your intentions were pure, that’s why I kept you from sinning against me; I was the one who kept you from going to bed with her. So now give the man’s wife back to him. He’s a prophet and will pray for you—pray for your life. If you don’t give her back, know that it’s certain death both for you and everyone in your family.”
