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.
And Sarah became with child, and gave Abraham a son when he was old, at the time named by God. And Abraham gave to his son, to whom Sarah had given birth, the name Isaac.
And Sarah said, God has given me cause for laughing, and everyone who has news of it will be laughing with me.
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. And you will be glad and have great delight; and numbers of people will have joy at his birth. For he will be great in the eyes of the Lord; he will not take wine or strong drink; and he will be full of the Spirit of God from his birth. And through him great numbers of the children of Israel will be turned to the Lord their God. And he will go before his face in the spirit and power of Elijah, turning the hearts of fathers to their children, and wrongdoers to the way of righteousness; to make ready a people whose hearts have been turned to the Lord. And Zacharias said to the angel, How may I be certain of this? For I am an old man, and my wife is far on in years. And the angel, answering, said, I am Gabriel, whose place is before God; I have been sent to say these words to you and to give you this good news. Now, see, you will be without voice or language till the day when these things come about, because you had not faith in my words, which will have effect at the right time.
But it is not as if the word of God was without effect. For they are not all Israel, who are of Israel: And they are not all children because they are the seed of Abraham; but, In Isaac will your seed be named. That is, it is not the children of the flesh, but the children of God's undertaking, who are named as the seed. For this is the word of God's undertaking, At this time will I come, and Sarah will have a son.
Now we, brothers, as Isaac was, are the children of the undertaking of God. But as in those days he who had birth after the flesh was cruel to him who had birth after the Spirit, even so it is now. What then do the Writings say? Send away the servant-woman and her son; for the son of the servant-woman will not have a part in the heritage with the son of the free woman. So, brothers, we are not children of the servant-woman, but of the free woman.
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. Now Abraham and Sarah were very old, and Sarah was past the time for giving birth. And Sarah, laughing to herself, said, Now that I am used up am I still to have pleasure, my husband himself being old? And the Lord said, Why was Sarah laughing and saying, Is it possible for me, being old, to give birth to a child? 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.
Keep in this land, and I will be with you and give you my blessing; for to you and to your seed will I give all these lands, giving effect to the oath which I made to your father Abraham;
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. 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.

CHAPTER 17
Ge 17:1-27. Renewal of the Covenant.
1. Abram … ninety years old and nine—thirteen years after the birth of Ishmael [Ge 16:16]. During that interval he had enjoyed the comforts of communion with God but had been favored with no special revelation as formerly, probably on account of his hasty and blameable marriage with Hagar.
the Lord appeared—some visible manifestation of the divine presence, probably the Shekinah or radiant glory of overpowering effulgence.
I am the Almighty God—the name by which He made Himself known to the patriarchs (Ex 6:3), designed to convey the sense of "all-sufficient" (Ps 16:5, 6; 73:25).
walk … and … perfect—upright, or sincere (Ps 51:6) in heart, speech, and behavior.
3. Abram fell on his face—the attitude of profoundest reverence assumed by Eastern people. It consists in the prostrate body resting on the hands and knees, with the face bent till the forehead touches the ground. It is an expression of conscious humility and profound reverence.
4. my covenant is with thee—Renewed mention is made of it as the foundation of the communication that follows. It is the covenant of grace made with all who believe in the Saviour.
5. but thy name shall be Abraham—In Eastern countries a change of name is an advertisement of some new circumstance in the history, rank, or religion of the individual who bears it. The change is made variously, by the old name being entirely dropped for the new, or by conjoining the new with the old; or sometimes only a few letters are inserted, so that the altered form may express the difference in the owner's state or prospects. It is surprising how soon a new name is known and its import spread through the country. In dealing with Abraham and Sarai, God was pleased to adapt His procedure to the ideas and customs of the country and age. Instead of Abram, "a high father," he was to be called Abraham, "father of a multitude of nations" (see Re 2:17).
8. I will give unto thee … the land—It had been previously promised to Abraham and his posterity (Ge 15:18). Here it is promised as an "everlasting possession," and was, therefore, a type of heaven, "the better country" (Heb 11:16).
10. Every man child among you shall be circumcised—This was the sign in the Old Testament Church as baptism is in the New, and hence the covenant is called "covenant of circumcision" (Ac 7:8; Ro 4:11). The terms of the covenant were these: on the one hand Abraham and his seed were to observe the right of circumcision; and on the other, God promised, in the event of such observance, to give them Canaan for a perpetual possession, to be a God to him and his posterity, and that in him and his seed all nations should be blessed.
15, 16. As for Sarai … I will … give thee a son also of her—God's purposes are gradually made known. A son had been long ago promised to Abraham. Now, at length, for the first time he is informed that it was to be a child of Sarai.
17. Abraham fell upon his face, and laughed—It was not the sneer of unbelief, but a smile of delight at the improbability of the event (Ro 4:20).
18. O that Ishmael might live before thee—natural solicitude of a parent. But God's thoughts are not as man's thoughts [Isa 55:8].
19, 20. The blessings of the covenant are reserved for Isaac, but common blessings were abundantly promised to Ishmael; and though the visible Church did not descend from his family, yet personally he might, and it is to be hoped did, enjoy its benefits.
