Genesis 18:10-19

One of them said, “I’m coming back about this time next year. When I arrive, your wife Sarah will have a son.” Sarah was listening at the tent opening, just behind the man. Abraham and Sarah were old by this time, very old. Sarah was far past the age for having babies. Sarah laughed within herself, “An old woman like me? Get pregnant? With this old man of a husband?” GOD said to Abraham, “Why did Sarah laugh saying, ‘Me? Have a baby? An old woman like me?’ Is anything too hard for GOD? I’ll be back about this time next year and Sarah will have a baby.” Sarah lied. She said, “I didn’t laugh,” because she was afraid. But he said, “Yes you did; you laughed.” * * * When the men got up to leave, they set off for Sodom. Abraham walked with them to say good-bye. Then GOD said, “Shall I keep back from Abraham what I’m about to do? Abraham is going to become a large and strong nation; all the nations of the world are going to find themselves blessed through him. Yes, I’ve settled on him as the one to train his children and future family to observe GOD’s way of life, live kindly and generously and fairly, so that GOD can complete in Abraham what he promised him.”
