¹⁰ And he said, I will certainly come back to you in the spring, and Sarah your wife will have a son. And his words came to the ears of Sarah who was at the back of the tent-door.

² And Sarah became with child, and gave Abraham a son when he was old, at the time named by God.

²¹ But my agreement will be with Isaac, to whom Sarah will give birth a year from this time.

¹⁹ And God said, Not so; but Sarah, your wife, will have a son, and you will give him the name Isaac, and I will make my agreement with him for ever and with his seed after him.

²⁸ Now we, brothers, as Isaac was, are the children of the undertaking of God.

²³ Now the son by the servant-woman has his birth after the flesh; but the son by the free woman has his birth through the undertaking of God.

⁸ That is, it is not the children of the flesh, but the children of God's undertaking, who are named as the seed.

⁹ For this is the word of God's undertaking, At this time will I come, and Sarah will have a son.

¹³ But the angel said, Have no fear, Zacharias, for your prayer has come to the ears of God, and your wife Elisabeth will have a son, and his name will be John.

¹⁶ And Elisha said, At this time in the coming year you will have a son in your arms. And she said, No, my lord, O man of God, do not say what is false to your servant.

¹⁷ Then the woman became with child and gave birth to a son at the time named, in the year after, as Elisha had said to her.

³ And the angel of the Lord came to the woman, and said to her, See now! though you have never given birth to children, you will be with child and give birth to a son.

⁴ Now then take care to have no wine or strong drink and to take no unclean thing for food;

⁵ For you are with child and will give birth to a son; his hair is never to be cut, for the child is to be separate to God from his birth; and he will take up the work of freeing Israel from the hands of the Philistines.

¹⁵ And the voice of the angel of the Lord came to Abraham a second time from heaven,

¹⁶ Saying, I have taken an oath by my name, says the Lord, because you have done this and have not kept back from me your dearly loved only son,

¹³ And the Lord said, Why was Sarah laughing and saying, Is it possible for me, being old, to give birth to a child?

¹⁴ Is there any wonder which the Lord is not able to do? At the time I said, in the spring, I will come back to you, and Sarah will have a child.

¹⁶ And I will give her a blessing so that you will have a son by her: truly my blessing will be on her, and she will be the mother of nations: kings of peoples will be her offspring.

¹⁰ And the angel of the Lord said, Your seed will be greatly increased so that it may not be numbered.
