²³ However, the son by the handmaid was born according to the flesh, but the son by the free woman was born through promise.

¹¹ By faith, even Sarah herself received power to conceive, and she bore a child when she was past age, since she counted him faithful who had promised.

¹⁰ He said, "I will certainly return to you when the season comes round. Behold, Sarah your wife will have a son." Sarah heard in the tent door, which was behind him.

¹¹ Now Abraham and Sarah were old, well advanced in age. It had ceased to be with Sarah after the manner of women.

¹² Sarah laughed within herself, saying, "After I have grown old will I have pleasure, my lord being old also?"

¹³ Yahweh said to Abraham, "Why did Sarah laugh, saying, 'Will I really bear a child, yet I am old?'

¹⁴ Is anything too hard for Yahweh? At the set time I will return to you, when the season comes round, and Sarah will have a son."

¹ Yahweh visited Sarah as he had said, and Yahweh did to Sarah as he had spoken.

² Sarah conceived, and bore Abraham a son in his old age, at the set time of which God had spoken to him.

⁷ Neither, because they are Abraham's seed, are they all children. But, "In Isaac will your seed be called."

⁸ That is, it is not the children of the flesh who are children of God, but the children of the promise are counted as a seed.

¹⁵ God said to Abraham, "As for Sarai your wife, you shall not call her name Sarai, but her name will be Sarah.

¹⁶ I will bless her, and moreover I will give you a son by her. Yes, I will bless her, and she will be a mother of nations. Kings of peoples will come from her."

¹⁷ Then Abraham fell on his face, and laughed, and said in his heart, "Will a child be born to him who is one hundred years old? Will Sarah, who is ninety years old, give birth?"

¹⁸ Abraham said to God, "Oh that Ishmael might live before you!"

¹⁹ God said, "No, but Sarah, your wife, will bear you a son. You shall call his name Isaac.{Isaac means "he laughs."} I will establish my covenant with him for an everlasting covenant for his seed after him.

¹⁸ Who in hope believed against hope, to the end that he might become a father of many nations, according to that which had been spoken, "So will your seed be."

¹⁹ Without being weakened in faith, he didn't consider his own body, already having been worn out, (he being about a hundred years old), and the deadness of Sarah's womb.

²⁰ Yet, looking to the promise of God, he didn't waver through unbelief, but grew strong through faith, giving glory to God,

²¹ and being fully assured that what he had promised, he was able also to perform.

⁸ But what does it say? "The word is near you, in your mouth, and in your heart;" that is, the word of faith, which we preach:

²⁸ Now we, brothers, as Isaac was, are children of promise.

²⁹ But as then, he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now.
