Genesis 12:11-13

When he came close to Egypt and was about to enter, he said to Sarai his wife, “Here now, I know that you are a good-looking woman;

so that when the Egyptians see you, they will say, ‘This is his wife,’ and kill me but keep you alive.

Please say that you are my sister, so that it will go well with me for your sake, and so that I will stay alive because of you.”
