Genesis 20:1-3

Abraham and Abimelech

20:1 Abraham journeyed from there to the Negev region and settled between Kadesh and Shur. While he lived as a temporary resident in Gerar, 20:2 Abraham said about his wife Sarah, “She is my sister.” So Abimelech, king of Gerar, sent for Sarah and took her.

20:3 But God appeared to Abimelech in a dream at night and said to him, “You are as good as dead because of the woman you have taken, for she is someone else’s wife.”
