Genesis 12:10-14

10Now there was a famine in the land. So Abram went down to Egypt to live as an outsider there, because the famine was severe in the land.

11Just as he was about to enter Egypt he said to Sarai his wife, “Look, please, I know that you are an attractive woman.

12So when the Egyptians see you they’ll say, ‘This is his wife.’ And they’ll kill me; but you, they’ll let live.

13Please say that you are my sister, so that I’ll be treated well for your sake, and my life will be spared because of you.”

14When Abram came to Egypt, the Egyptians did see that the woman was very beautiful.
