But God replied, “No—Sarah, your wife, will give birth to a son for you. You will name him Isaac, and I will confirm my covenant with him and his descendants as an everlasting covenant.
“I will confirm my covenant with you and your descendants after you, from generation to generation. This is the everlasting covenant: I will always be your God and the God of your descendants after you.
I will cause your descendants to become as numerous as the stars of the sky, and I will give them all these lands. And through your descendants all the nations of the earth will be blessed.
Your descendants will be as numerous as the dust of the earth! They will spread out in all directions—to the west and the east, to the north and the south. And all the families of the earth will be blessed through you and your descendants.
