Genesis 20:1-3

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.”
