Genesis 12:11-16

11And it came to pass when he was come near to enter into Egypt, that he said to Sarai his wife, Behold now, I know that thou art a woman fair to look upon.

12And it will come to pass when the Egyptians see thee, that they will say, She is his wife; and they will slay me, and save thee alive.

13Say, I pray thee, thou art my sister, that it may be well with me on thy account, and my soul may live because of thee.

14And it came to pass when Abram came into Egypt, that the Egyptians beheld the woman that she was very fair.

15And the princes of Pharaoh saw her, and praised her to Pharaoh; and the woman was taken into Pharaoh's house.

16And he treated Abram well on her account; and he had sheep, and oxen, and he-asses, and bondmen, and bondwomen, and she-asses, and camels.
