171 And Abram is a son of ninety and nine years, and Jehovah appeareth unto Abram, and saith unto him, 'I 'am' God Almighty, walk habitually before Me, and be thou perfect; 2 and I give My covenant between Me and thee, and multiply thee very exceedingly.' 3 And Abram falleth upon his face, and God speaketh with him, saying,
4 'I—lo, My covenant 'is' with thee, and thou hast become father of a multitude of nations; 5 and thy name is no more called Abram, but thy name hath been Abraham, for father of a multitude of nations have I made thee; 6 and I have made thee exceeding fruitful, and made thee become nations, and kings go out from thee.
7 'And I have established My covenant between Me and thee, and thy seed after thee, to their generations, for a covenant age-during, to become God to thee, and to thy seed after thee; 8 and I have given to thee, and to thy seed after thee, the land of thy sojournings, the whole land of Canaan, for a possession age-during, and I have become their God.' 9 And God saith unto Abraham, 'And thou dost keep My covenant, thou and thy seed after thee, to their generations; 10 this 'is' My covenant which ye keep between Me and you, and thy seed after thee: Every male of you 'is' to be circumcised; 11 and ye have circumcised the flesh of your foreskin, and it hath become a token of a covenant between Me and you. 12 'And a son of eight days is circumcised by you; every male to your generations, born in the house, or bought with money from any son of a stranger, who is not of thy seed; 13 he is certainly circumcised who 'is' born in thine house, or bought with thy money; and My covenant hath become in your flesh a covenant age-during; 14 and an uncircumcised one, a male, the flesh of whose foreskin is not circumcised, even that person hath been cut off from his people; My covenant he hath broken.'
15 And God saith unto Abraham, 'Sarai thy wife—thou dost not call her name Sarai, for Sarah 'is' her name; 16 and I have blessed her, and have also given to thee a son from her; and I have blessed her, and she hath become nations—kings of peoples are from her.' 17 And Abraham falleth upon his face, and laugheth, and saith in his heart, 'To the son of an hundred years is one born? or doth Sarah—daughter of ninety years—bear?' 18 And Abraham saith unto God, 'O that Ishmael may live before Thee;' 19 and God saith, 'Sarah thy wife is certainly bearing a son to thee, and thou hast called his name Isaac, and I have established My covenant with him, for a covenant age-during, to his seed after him. 20 As to Ishmael, I have heard thee; lo, I have blessed him, and made him fruitful, and multiplied him, very exceedingly; twelve princes doth he beget, and I have made him become a great nation; 21 and My covenant I establish with Isaac, whom Sarah doth bear to thee at this appointed time in the next year;'

The covenant was to be accomplished in due time. The promised Seed was Christ, and Christians in him. And all who are of faith are blessed with faithful Abram, being partakers of the same covenant blessings. In token of this covenant his name was changed from Abram, "a high father," to Abraham, "the father of a multitude." All that the Christian world enjoys, it is indebted for to Abraham and his Seed.

(Read Genesis 17:7-14)
The covenant of grace is from everlasting in the counsels of it, and to everlasting in the consequences of it. The token of the covenant was circumcision. It is here said to be the covenant which Abraham and his seed must keep. Those who will have the Lord to be to them a God, must resolve to be to him a people. Not only Abraham and Isaac, and his posterity by Isaac, were to be circumcised, but also Ishmael and the bond-servants. It sealed not only the covenant of the land of Canaan to Isaac's posterity, but of heaven, through Christ, to the whole church of God. The outward sign is for the visible church; the inward seal of the Spirit is peculiar to those whom God knows to be believers, and he alone can know them. The religious observance of this institution was required, under a very severe penalty. It is dangerous to make light of Divine institutions, and to live in the neglect of them. The covenant in question was one that involved great blessings for the world in all future ages. Even the blessedness of Abraham himself, and all the rewards conferred upon him, were for Christ's sake. Abraham was justified, as we have seen, not by his own righteousness, but by faith in the promised Messiah.
Commentary on Genesis 17:15-22
(Read Genesis 17:15-22)
Here is the promise made to Abraham of a son by Sarai, in whom the promise made to him should be fulfilled. The assurance of this promise was the change of Sarai's name into Sarah. Sarai signifies my princess, as if her honour were confined to one family only; Sarah signifies a princess. The more favours God confers upon us, the more low we should be in our own eyes. Abraham showed great joy; he laughed, it was a laughter of delight, not of distrust. Now it was that Abraham rejoiced to see Christ's day; now he saw it and was glad, John 8:56. Abraham, dreading lest Ishmael should be abandoned and forsaken of God, put up a petition on his behalf. God gives us leave in prayer to be particular in making known our requests. Whatever is our care and fear, should be spread before God in prayer. It is the duty of parents to pray for their children, and the great thing we should desire is, that they may be kept in covenant with Him, and may have grace to walk before him in uprightness. Common blessings are secured to Ishmael. Outward good things are often given to those children of godly parents who are born after the flesh, for their parents' sake. Covenant blessings are reserved for Isaac, and appropriated to him.
