Genesis 20:1-7

Abraham journeyed from the oaks of Mamre to the southern region of Canaan and settled between Kadesh and Shur, to live as a temporary resident in Gerar. Now Abraham had said about his wife Sarah, “She’s my sister.” So Abimelech, king of Gerar, sent for her and took her into his harem. One night, God appeared to Abimelech in a dream and said to him, “You’re as good as dead, for you have taken into your harem a married woman!” Now Abimelech had not touched Sarah, so he said to the Lord, “Would you really destroy people who are innocent? Didn’t the man tell me, ‘She is my sister’? And didn’t she agree and say, ‘Yes, he’s my brother’? I’ve done this with clean hands and a clear conscience.” Then God answered him in the dream, “Yes, I know you did this with a clear conscience. Furthermore, it was I who kept you from sinning and kept you from touching her. Now return the man’s wife, and because he is a prophet, he will intercede on your behalf that you may live. But if you don’t give her back—you will certainly die, you and your entire household.”
