Thematic Bible: Isaac, in calling his wife his sister

And the men of the place will ask concerning his wife; and he will say, She is my sister: for he will be afraid to say, My wife, lest the men of the place will kill me for Rebekah, because she is good in appearance. And it was when the days there were long to him, and Abimelech king of the Philistines shall bend forward through the window, and will see, and behold, Isaak playing with Rebekah his wife. And Abimelech will call to Isaak, and will say, Surely, behold, she thy wife; and how saidst thou, She is my sister? And Isaak will say to him, Because I said, Lest I shall die for her.
