One of them said, “Nine months from now I will come back, and your wife Sarah will have a son.” Sarah was behind him, at the door of the tent, listening.
I will bless her, and I will give you a son by her. I will bless her, and she will become the mother of nations, and there will be kings among her descendants.”
But God said, “No. Your wife Sarah will bear you a son and you will name him Isaac. I will keep my covenant with him and with his descendants forever. It is an everlasting covenant.
But the angel said to him, “Don't be afraid, Zechariah! God has heard your prayer, and your wife Elizabeth will bear you a son. You are to name him John.
