Genesis 20:6-7

Then God said to Abimelech in the dream, “Yes, I know that you did not realize what you were doing. So I did not allow you to sin against me. I did not allow you to sleep with her. Give Abraham his wife back. He is a prophet. He will pray for you, and you will not die. But if you do not give Sarah back, you will die. And all your family will surely die.”
