Gen 12.14 And it came to pass, that, when Abram was come into Egypt, the Egyptians beheld the woman that she was very fair.
Gen 26.7 And the men of the place asked him of his wife; and he said, She is my sister: for he feared to say, She is my wife; lest, said he, the men of the place should kill me for Rebekah; because she was fair to look upon.
