Gen 17:20, 21:13 | MHC | STEP | 15 And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be. 16 And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her. 17 Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is a hundred years old? and shall Sarah, that is ninety years old, bear? 18 And Abraham said unto God, O that Ishmael might live before thee! 19 And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him. 20 And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. 21 But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year. 22 And he left off talking with him, and God went up from Abraham. Here is, I. The promise made to Abraham of a son by Sarai, that son in whom the promise made to him should be fulfilled, that he should be the father of many nations; for she also shall be a mother of nations, and kings of people shall be of her, . Note, 1. God reveals the purposes of his good-will to his people by degrees. God had told Abraham long before that he should have a son, but never till now that he should have a son by Sarai. 2. The blessing of the Lord makes fruitful, and adds no sorrow with it, no such sorrow as was in Hagar's case. "I will bless her with the blessing of fruitfulness, and then thou shalt have a son of her." 3. Civil government and order are a great blessing to the church. It is promised, not only that people, but kings of people, should be of her; not a headless rout, but a well-modelled well-governed society. II. The ratification of this promise was the change of Sarai's name into Sarah ( ), the same letter being added to her name that was to Abraham's, and for the same reasons. Sarai signifies my princess, as if her honour were confined to one family only. Sarah signifies a princess --namely, of multitudes, or signifying that from her should come the Messiah the prince, even the prince of the kings of the earth. III. Abraham's joyful, thankful, entertainment of this gracious promise, . Upon this occasion he expressed, 1. Great humility: He fell on his face. Note, The more honours and favours God confers upon us the lower we should be in our own eyes, and the more reverent and submissive before God. 2. Great joy: He laughed. It was a laughter of delight, not of distrust. Note, Even the promises of a holy God, as well as his performances, are the joys of holy souls; there is the joy of faith as well as the joy of fruition. Now it was that Abraham rejoiced to see Christ's day. Now he saw it and was glad ( ); for, as he saw heaven in the promise of Canaan, so he saw Christ in the promise of Isaac. 3. Great admiration: Shall a child be born to him that is a hundred years old? He does not here speak of it as at all doubtful (for we are sure that he staggered not at the promise, ), but as very wonderful and that which could not be effected but by the almighty power of God, and as very kind, and a favour which was the more affecting and obliging for this, that it was extremely surprising, . IV. Abraham's prayer for Ishmael: O that Ishmael might live before thee! . This he speaks, not as desiring that Ishmael might be preferred before the son he should have by Sarah; but, dreading lest he should be abandoned and forsaken of God, he puts up this petition on his behalf. Now that God is talking with him he thinks he has a very fair opportunity to speak a good word for Ishmael, and he will not let it slip. Note, 1. Though we ought not to prescribe to God, yet he gives us leave, in prayer, to be humbly free with him, and particular in making known our requests, . Whatever is the matter of our care and fear should be spread before God in prayer. 2. It is the duty of parents to pray for their children, for all their children, as Job, who offered burnt offerings according to the number of them all, . Abraham would not have it thought that, when God promised him a son by Sarah, which he so much desired, then his son by Hagar was forgotten; no, still he bears him upon his heart, and shows a concern for him. The prospect of further favours must not make us unmindful of former favours. 3. The great thing we should desire of God for our children is that they may live before him, that is, that they may be kept in covenant with him, and may have grace to walk before him in their uprightness. Spiritual blessings are the best blessings, and those for which we should be most earnest with God, both for ourselves and others. Those live well that live before God. V. God's answer to his prayer; and it is an answer of peace. Abraham could not say that he sought God's face in vain. 1. Common blessings are secured to Ishmael ( : As for Ishmael, whom thou art in so much care about, I have heard thee; he shall find favour for thy sake; I have blessed him, that is, I have many blessings in store for him. (1.) His posterity shall be numerous: I will multiply him exceedingly, more than his neighbours. This is the fruit of the blessing, as that, . (2.) They shall be considerable: Twelve princes shall he beget. We may charitably hope that spiritual blessings also were bestowed upon him, though the visible church was not brought out of his loins and the covenant was not lodged in his family. Note, Great plenty of outward good things is often given to those children of godly parents who are born after the flesh, for their parents' sake. 2. Covenant blessings are reserved for Isaac, and appropriated to him, . If Abraham, in his prayer for Ishmael, meant that he would have the covenant made with him, and the promised seed to come from him, then God did not answer him in the letter, but in that which was equivalent, nay, which was every way better. (1.) God repeats to him the promise of a son by Sarah: She shall bear thee a son indeed. Note, Even true believers need to have God's promises doubled and repeated to them, that they may have strong consolation, . Again, Children of the promise are children indeed. (2.) He names that child--calls him Isaac, laughter, because Abraham rejoiced in spirit when this son was promised him. Note, If God's promises be our joy, his mercies promised shall in due time be our exceeding joy. Christ will be laughter to those that look for him; those that now rejoice in hope shall shortly rejoice in having that which they hope for: this is laughter that is not mad. (3.) He entails the covenant upon that child: I will establish my covenant with him. Note, God takes whom he pleases into covenant with himself, according to the good pleasure of his will. See . Thus was the covenant settled between God and Abraham, with its several limitations and remainders, and then the conference ended: God left off talking with him, and the vision disappeared, God went up from Abraham. Note, Our communion with God here is broken and interrupted; in heaven it will be a continual and everlasting feast.

Genesis 17:20

15 And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be. 16 And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her. 17 Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is a hundred years old? and shall Sarah, that is ninety years old, bear? 18 And Abraham said unto God, O that Ishmael might live before thee! 19 And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him. 20 And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. 21 But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year. 22 And he left off talking with him, and God went up from Abraham.

Here is, I. The promise made to Abraham of a son by Sarai, that son in whom the promise made to him should be fulfilled, that he should be the father of many nations; for she also shall be a mother of nations, and kings of people shall be of her, v. 16. Note, 1. God reveals the purposes of his good-will to his people by degrees. God had told Abraham long before that he should have a son, but never till now that he should have a son by Sarai. 2. The blessing of the Lord makes fruitful, and adds no sorrow with it, no such sorrow as was in Hagar's case. "I will bless her with the blessing of fruitfulness, and then thou shalt have a son of her." 3. Civil government and order are a great blessing to the church. It is promised, not only that people, but kings of people, should be of her; not a headless rout, but a well-modelled well-governed society.

II. The ratification of this promise was the change of Sarai's name into Sarah (v. 15), the same letter being added to her name that was to Abraham's, and for the same reasons. Sarai signifies my princess, as if her honour were confined to one family only. Sarah signifies a princess--namely, of multitudes, or signifying that from her should come the Messiah the prince, even the prince of the kings of the earth.

III. Abraham's joyful, thankful, entertainment of this gracious promise, v. 17. Upon this occasion he expressed, 1. Great humility: He fell on his face. Note, The more honours and favours God confers upon us the lower we should be in our own eyes, and the more reverent and submissive before God. 2. Great joy: He laughed. It was a laughter of delight, not of distrust. Note, Even the promises of a holy God, as well as his performances, are the joys of holy souls; there is the joy of faith as well as the joy of fruition. Now it was that Abraham rejoiced to see Christ's day. Now he saw it and was glad (John viii. 56); for, as he saw heaven in the promise of Canaan, so he saw Christ in the promise of Isaac. 3. Great admiration: Shall a child be born to him that is a hundred years old? He does not here speak of it as at all doubtful (for we are sure that he staggered not at the promise, Rom. iv. 20), but as very wonderful and that which could not be effected but by the almighty power of God, and as very kind, and a favour which was the more affecting and obliging for this, that it was extremely surprising, Ps. cxxvi. 1, 2.

IV. Abraham's prayer for Ishmael: O that Ishmael might live before thee! v. 18. This he speaks, not as desiring that Ishmael might be preferred before the son he should have by Sarah; but, dreading lest he should be abandoned and forsaken of God, he puts up this petition on his behalf. Now that God is talking with him he thinks he has a very fair opportunity to speak a good word for Ishmael, and he will not let it slip. Note, 1. Though we ought not to prescribe to God, yet he gives us leave, in prayer, to be humbly free with him, and particular in making known our requests, Phil. iv. 6. Whatever is the matter of our care and fear should be spread before God in prayer. 2. It is the duty of parents to pray for their children, for all their children, as Job, who offered burnt offerings according to the number of them all, Job i. 5. Abraham would not have it thought that, when God promised him a son by Sarah, which he so much desired, then his son by Hagar was forgotten; no, still he bears him upon his heart, and shows a concern for him. The prospect of further favours must not make us unmindful of former favours. 3. The great thing we should desire of God for our children is that they may live before him, that is, that they may be kept in covenant with him, and may have grace to walk before him in their uprightness. Spiritual blessings are the best blessings, and those for which we should be most earnest with God, both for ourselves and others. Those live well that live before God.

V. God's answer to his prayer; and it is an answer of peace. Abraham could not say that he sought God's face in vain.

1. Common blessings are secured to Ishmael (v. 20): As for Ishmael, whom thou art in so much care about, I have heard thee; he shall find favour for thy sake; I have blessed him, that is, I have many blessings in store for him. (1.) His posterity shall be numerous: I will multiply him exceedingly, more than his neighbours. This is the fruit of the blessing, as that, ch. i. 28. (2.) They shall be considerable: Twelve princes shall he beget. We may charitably hope that spiritual blessings also were bestowed upon him, though the visible church was not brought out of his loins and the covenant was not lodged in his family. Note, Great plenty of outward good things is often given to those children of godly parents who are born after the flesh, for their parents' sake.

2. Covenant blessings are reserved for Isaac, and appropriated to him, v. 19, 21. If Abraham, in his prayer for Ishmael, meant that he would have the covenant made with him, and the promised seed to come from him, then God did not answer him in the letter, but in that which was equivalent, nay, which was every way better. (1.) God repeats to him the promise of a son by Sarah: She shall bear thee a son indeed. Note, Even true believers need to have God's promises doubled and repeated to them, that they may have strong consolation, Heb. vi. 18. Again, Children of the promise are children indeed. (2.) He names that child--calls him Isaac, laughter, because Abraham rejoiced in spirit when this son was promised him. Note, If God's promises be our joy, his mercies promised shall in due time be our exceeding joy. Christ will be laughter to those that look for him; those that now rejoice in hope shall shortly rejoice in having that which they hope for: this is laughter that is not mad. (3.) He entails the covenant upon that child: I will establish my covenant with him. Note, God takes whom he pleases into covenant with himself, according to the good pleasure of his will. See Rom. ix. 8, 18. Thus was the covenant settled between God and Abraham, with its several limitations and remainders, and then the conference ended: God left off talking with him, and the vision disappeared, God went up from Abraham. Note, Our communion with God here is broken and interrupted; in heaven it will be a continual and everlasting feast.

Genesis 21:13

9 And Sarah saw the son of Hagar the Egyptian, which she had borne unto Abraham, mocking. 10 Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac. 11 And the thing was very grievous in Abraham's sight because of his son. 12 And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Isaac shall thy seed be called. 13 And also of the son of the bondwoman will I make a nation, because he is thy seed.

The casting out of Ishmael is here considered of, and resolved on.

I. Ishmael himself gave the occasion by some affronts he gave to Isaac his little brother, some think on the day that Abraham made the feast for joy that Isaac was safely weaned, which the Jews say was not till he was three years old, others say five. Sarah herself was an eye-witness of the abuse: she saw the son of the Egyptian mocking (v. 9), mocking Isaac, no doubt, for it is said, with reference to this (Gal. iv. 29), that he that was born after the flesh persecuted him that was born after the Spirit. Ishmael is here called the son of the Egyptian, because, as some think, the 400 years' affliction of the seed of Abraham by the Egyptians began now, and was to be dated hence, ch. xv. 13. She saw him playing with Isaac, so the LXX., and, in play, mocking him. Ishmael was fourteen years older than Isaac; and, when children are together, the elder should be careful and tender of the younger: but it argued a very base and sordid disposition in Ishmael to be abusive to a child that was no way a match for him. Note, 1. God takes notice of what children say and do in their play, and will reckon with them if they say or do amiss, though their parents do not. 2. Mocking is a great sin, and very provoking to God. 3. There is a rooted remaining enmity in the seed of the serpent against the seed of the woman. The children of promise must expect to be mocked. This is persecution, which those that will live godly must count upon. 4. None are rejected and cast out from God but those who have first deserved it. Ishmael is continued in Abraham's family till he becomes a disturbance, grief, and scandal to it.

II. Sarah made the motion: Cast out this bond-woman, v. 10. This seems to be spoken in some heat, yet it is quoted (Gal. iv. 30) as if it had been spoken by a spirit of prophecy; and it is the sentence passed on all hypocrites and carnal people, though they have a place and a name in the visible church. All that are born after the flesh and not born again, that rest in the law and reject the gospel promise, shall certainly be cast out. It is made to point particularly at the rejection of the unbelieving Jews, who, though they were the seed of Abraham, yet, because they submitted not to the gospel covenant, were unchurched and disfranchised: and that which, above any thing, provoked God to cast them off was their mocking and persecuting the gospel church, God's Isaac, in its infancy, 1 Thess. ii. 16. Note, There are many who are familiarly conversant with the children of God in this world, and yet shall not partake with them in the inheritance of sons. Ishmael might be Isaac's play-fellow and school-fellow, yet not his fellow-heir.

III. Abraham was averse to it: The thing was very grievous in Abraham's sight, v. 11. 1. It grieved him that Ishmael had given such a provocation. Note, Children ought to consider that the more their parents love them the more they are grieved at their misconduct, and particularly at their quarrels among themselves. 2. It grieved him that Sarah insisted upon such a punishment. "Might it not suffice to correct him? would nothing less serve than to expel him?" Note, Even the needful extremities which must be used with wicked and incorrigible children are very grievous to tender parents, who cannot thus afflict willingly.

IV. God determined it, v. 12, 13. We may well suppose Abraham to be greatly agitated about this matter, loth to displease Sarah, and yet loth to expel Ishmael; in this difficulty God tells him what his will is, and then he is satisfied. Note, A good man desires no more in doubtful cases than to know his duty, and what God would have him do; and, when he is clear in this, he is, or should be, easy. To make Abraham so, God sets this matter before him in a true light, and shows him, 1. That the casting out of Ishmael was necessary to the establishment of Isaac in the rights and privileges of the covenant: In Isaac shall thy seed be called. Both Christ and the church must descend from Abraham through the loins of Isaac; this is the entail of the promise upon Isaac, and is quoted by the apostle (Rom. ix. 7) to show that not all who come from Abraham's loins were the heirs of Abraham's covenant. Isaac, the promised son, must be the father of the promised seed; therefore, "Away with Ishmael, send him far enough, lest he corrupt the manners or attempt to invade the rights of Isaac." It will be his security to have his rival banished. The covenant seed of Abraham must be a peculiar people, a people by themselves, from the very first, distinguished, not mingled with those that were out of covenant; for this reason Ishmael must be separated. Abraham was called alone, and so must Isaac be. See Isa. li. 2. It is probable that Sarah little thought of this (John xi. 51), but God took what she said, and turned it into an oracle, as afterwards, ch. xxvii. 10. 2. That the casting out of Ishmael should not be his ruin, v. 13. He shall be a nation, because he is thy seed. We are not sure that it was his eternal ruin. It is presumption to say that all those who are left out of the external dispensation from all his mercies: those may be saved who are not thus honoured. However, we are sure it was not his temporal ruin. Though he was chased out of the church, he was not chased out of the world. I will make him a nation. Note, (1.) Nations are of God's making: he founds them, he forms them, he fixes them. (2.) Many are full of the blessings of God's providence that are strangers to the blessings of his covenant. (3.) The children of this world often fare the better, as to outward things, for their relation to the children of God.
