Genesis 12:13

10 And there was a famine in the land: and Abram went down into Egypt to dwell there; for the famine [was] grievous in the land.

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

12 Therefore it will come to pass, when the Egyptians shall see thee, that they will say, This [is] his wife: and they will kill me, but they will save thee alive.

13 Say, I pray thee, thou [art] my sister: that it may be well with me for thy sake; and my soul shall live because of thee.

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

15 The princes also of Pharaoh saw her, and commended her before Pharaoh: and the woman was taken into Pharaoh's house.

16 And he treated Abram well for her sake: and he had sheep, and oxen, and he-asses, and men-servants, and maid-servants, and she-asses, and camels.
