And he said, I will certainly return to you according to the time of life; and, lo, Sarah your wife shall have a son. And Sarah heard it in the tent door, which was behind him.
And I will bless her, and give you a son also from her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be from her.
And God said, Sarah your wife shall bear you a son indeed; and you shall call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his descendents after him.
But the angel said to him, Fear not, Zacharias: for your prayer is heard; and your wife Elizabeth shall bear you a son, and you shall call his name John.
