Genesis 20

1 And Abraham journeyed from there to the South, and dwelt between Kadesh and Shur, and stayed in Gerar. 2 Now 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, “Indeed you are a dead man because of the woman whom you have taken, for she is a man’s wife.” . . .
