Genesis 20:1-7

Abraham left Hebron and traveled to southern Canaan where he stayed awhile between Kadesh and Shur. When he moved to Gerar, he told people that his wife Sarah was his sister. Abimelech king of Gerar heard this, so he sent some servants to take her. But one night God spoke to Abimelech in a dream and said, “You will die. The woman you took is married.” But Abimelech had not gone near Sarah, so he said, “Lord, would you destroy an innocent nation? Abraham himself told me, ‘This woman is my sister,’ and she also said, ‘He is my brother.’ I am innocent. I did not know I was doing anything wrong.” Then God said to Abimelech in the dream, “Yes, I know you did not realize what you were doing. So I did not allow you to sin against me and touch her. Give Abraham his wife back. He is a prophet. He will pray for you, and you will not die. But if you do not give Sarah back, you and all your family will surely die.”
