Genesis 26:7-9

Amplified Bible, Classic Edition

⁷ And the men of the place asked him about his wife, and he said, She is my sister; for he was afraid to say, She is my wife—[thinking], Lest the men of the place should kill me for Rebekah, because she is attractive and is beautiful to look upon.

⁸ When he had been there a long time, Abimelech king of the Philistines looked out of a window and saw Isaac caressing Rebekah his wife.

⁹ And Abimelech called Isaac and said, See here, she is certainly your wife! How did you [dare] say to me, She is my sister? And Isaac said to him, Because I thought, Lest I die on account of her.
