Genesis 12:10

8He left from there to go to the mountain on the east of Bethel and pitched his tent, having Bethel on the west, and Ai on the east. There he built an altar to the LORD and called on the LORD’s name.

9Abram traveled, still going on toward the South.

10There was a famine in the land. Abram went down into Egypt to live as a foreigner there, for the famine was severe in the land.

11When he had come near to enter Egypt, he said to Sarai his wife, “See now, I know that you are a beautiful woman to look at.

12It will happen that when the Egyptians see you, they will say, ‘This is his wife.’ They will kill me, but they will save you alive.
