Genesis 12:10-20

10And there was a famine in the land: and Abram went down into Egypt to dwell there; for the famine was grievous in the land. 11And 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: 12Therefore it shall come to pass, when the Egyptians shall see thee, that they shall say, This is his wife: and they will kill me, but they will save thee alive. 13Say, 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.

14And it came to pass, that, when Abram had come into Egypt, the Egyptians beheld the woman that she was very fair. 15The princes also of Pharaoh saw her, and commended her before Pharaoh: and the woman was taken into Pharaoh’s house. 16And he treated Abram well for her sake: and he had sheep, and oxen, and male donkeys, and male and female servants, and female donkeys, and camels. 17And the LORD afflicted Pharaoh and his house with great plagues because of Sarai Abram’s wife. 18And Pharaoh called Abram, and said, What is this that thou hast done to me? why didst thou not tell me that she is thy wife? 19Why saidst thou, She is my sister? so I might have taken her to me for a wife: now therefore behold thy wife, take her, and go thy way. 20And Pharaoh commanded his men concerning him: and they sent him away, and his wife, and all that he had.
