Genesis 12:10-16

Now there was a famine in the land; and Abram went down into Egypt to live temporarily, for the famine in the land was oppressive and severe. And when he was about to enter Egypt, he said to Sarai his wife, “Listen: I know that you are a beautiful woman; so when the Egyptians see you, they will say, ‘This is his wife’; and they will kill me [to acquire you], but they will let you live. Please tell them that you are my sister so that things will go well for me for your sake, and my life will be spared because of you.” And when Abram entered Egypt, the Egyptians saw that Sarai was very beautiful. Pharaoh’s princes (officials) also saw her and praised her to Pharaoh; and the woman was taken [for the purpose of marriage] into Pharaoh’s house (harem). Therefore Pharaoh treated Abram well for her sake; he acquired sheep, oxen, male and female donkeys, male and female servants, and camels.
