Genesis 12:13-20 New Revised Standard Version (NRSV)
13 Say you are my sister, so that it may go well with me because of you, and that my life may be spared on your account.” 14 When Abram entered Egypt the Egyptians saw that the woman was very beautiful. 15 When the officials of Pharaoh saw her, they praised her to Pharaoh. And the woman was taken into Pharaoh’s house. 16 And for her sake he dealt well with Abram; and he had sheep, oxen, male donkeys, male and female slaves, female donkeys, and camels.
17 But the Lord afflicted Pharaoh and his house with great plagues because of Sarai, Abram’s wife. 18 So Pharaoh called Abram, and said, “What is this you have done to me? Why did you not tell me that she was your wife? 19 Why did you say, ‘She is my sister,’ so that I took her for my wife? Now then, here is your wife, take her, and be gone.” 20 And Pharaoh gave his men orders concerning him; and they set him on the way, with his wife and all that he had.
