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.
Sarah conceived, and bore Abraham a son in his old age, at the set time of which God had spoken to him. Abraham called his son who was born to him, whom Sarah bare to him, Isaac.{Isaac means "He laughs."}
But the angel said to him, "Don't be afraid, Zacharias, because your request has been heard, and your wife, Elizabeth, will bear you a son, and you shall call his name John. You will have joy and gladness; and many will rejoice at his birth. For he will be great in the sight of the Lord, and he will drink no wine nor strong drink. He will be filled with the Holy Spirit, even from his mother's womb. He will turn many of the children of Israel to the Lord, their God. He will go before him in the spirit and power of Elijah, 'to turn the hearts of the fathers to the children,' and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord." Zacharias said to the angel, "How can I be sure of this? For I am an old man, and my wife is well advanced in years." The angel answered him, "I am Gabriel, who stands in the presence of God. I was sent to speak to you, and to bring you this good news. Behold, you will be silent and not able to speak, until the day that these things will happen, because you didn't believe my words, which will be fulfilled in their proper time."
But it is not as though the word of God has come to nothing. For they are not all Israel, that are of Israel. Neither, because they are Abraham's seed, are they all children. But, "In Isaac will your seed be called." 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. For this is a word of promise, "At the appointed time I will come, and Sarah will have a son."
Now we, brothers, as Isaac was, are children of promise. 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. However what does the Scripture say? "Throw out the handmaid and her son, for the son of the handmaid will not inherit with the son of the free woman." So then, brothers, we are not children of a handmaid, but of the free woman.
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. Now Abraham and Sarah were old, well advanced in age. It had ceased to be with Sarah after the manner of women. Sarah laughed within herself, saying, "After I have grown old will I have pleasure, my lord being old also?" Yahweh said to Abraham, "Why did Sarah laugh, saying, 'Will I really bear a child, yet I am old?' 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."

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.
