Genesis 26:9

So Abimelech called Isaac and said , Behold , she is your wife . How then could you say , She is my sister ? Isaac said to him, Because I thought , Lest I die because of her.

So Abimelek summoned Isaac and said, “She is really your wife! Why did you say, ‘She is my sister`?” Isaac answered him, “Because I thought I might lose my life on account of her.”

And Abimelech called Isaac, and said, Behold, of a surety she is thy wife : and how saidst thou, She is my sister? And Isaac said unto him, Because I said, Lest I die for her.
