Genesis 20:1-3

King James Version

20 And Abraham journeyed from thence toward the south country, and dwelled between Kadesh and Shur, and sojourned in Gerar.

² And Abraham said of Sarah his wife, She is my sister: and Abimelech king of Gerar sent, and took Sarah.

³ But God came to Abimelech in a dream by night, and said to him, Behold, thou art but a dead man, for the woman which thou hast taken; for she is a man's wife.
