Thematic Bible: Isaac, in calling his wife his sister

When the men of the place asked about his wife, he said, "She is my sister," for he was afraid to say, "my wife," thinking, "the men of the place might kill me on account of Rebekah, for she is beautiful." It came about, when he had been there a long time, that Abimelech king of the Philistines looked out through a window, and saw, and behold, Isaac was caressing his wife Rebekah. Then Abimelech called Isaac and said, "Behold, certainly she is your wife! How then did you say, 'She is my sister'?" And Isaac said to him, "Because I said, 'I might die on account of her.'"
