Genesis 26:9 DBY

⁷  And the men of the place asked about his wife. And he said, She is my sister; for he feared to say, my wife, [saying to himself,] Lest the men of the place slay me on account of Rebecca -- because she was fair in countenance.

⁸  And it came to pass when he had been there some time, that Abimelech the king of the Philistines looked out of the window, and saw, and behold, Isaac was dallying with Rebecca his wife.

⁹  Then Abimelech called Isaac, and said, Behold, she is certainly thy wife; and how saidst thou, She is my sister? and Isaac said to him, Because I said, Lest I die on account of her.

¹⁰  And Abimelech said, What is this thou hast done to us? But a little and one of the people might have lain with thy wife, and thou wouldest have brought a trespass on us.

¹¹  And Abimelech charged all the people, saying, He that touches this man or his wife shall certainly be put to death.
