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 (Gen 21:9), mocking Isaac, no doubt, for it is said, with reference to this (Gal 4:29), 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, Gen 15:13. She saw him playing with Isaac, so the Septuagint, 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, Gen 21:10. This seems to be spoken in some heat, yet it is quoted (Gal 4:30) 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, Th1 2:16, 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, Gen 21:11. 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, Gen 21:12, Gen 21:13. 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 9:7) 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 51:2. It is probable that Sarah little thought of this (Joh 11:51), but God took what she said, and turned it into an oracle, as afterwards, Gen 27:10. 2. That the casting out of Ishmael should not be his ruin, Gen 21:13. 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.

In Isaac shall thy seed be called - Here God shows the propriety of attending to the counsel of Sarah; and lest Abraham, in whose eyes the thing was grievous, should feel distressed on the occasion, God renews his promises to Ishmael and his posterity.

And Abraham rose up early in the morning,.... It was in the night the Lord spoke to him, and bid him hearken to the voice of Sarah; and, as soon as it was morning, he arose, and was not disobedient to the heavenly vision; for, though the thing he was directed to was disagreeable to flesh and blood, and contrary to his natural affection, yet, it being the will of God, he readily complied with it:

and took bread and a bottle of water; a loaf of bread very probably, and a leathern or wooden bottle of water, as Aben Ezra supposes it to be; for there is no need to say that these are put for all necessaries, and a liberal provision that might be made by Abraham; but it is to be taken strictly, according to the letter and history, as a matter of fact, since it could be no more than Hagar could carry, and did carry upon her shoulder: and, though Abraham could have sent cattle laden with provisions, and servants to attend them, yet he did not, which his natural affection and liberal disposition might dictate to him; but, as he was to hearken in this affair to whatsoever Sarah said, and act accordingly, perhaps this was all she would grant; or it might be so ordered by the providence of God, as a chastisement for their ill behaviour, and that they might know the difference between being in Abraham's house and out of it; and that there might be an opportunity given to show favour to them for Abraham's sake, who might probably direct them to some place where to go; and, till they came there, this might be a sufficient supply, when he gave them reason to expect more from him; but they got into the wilderness, wandered about and lost their way, and so became destitute of provisions; and this may be an emblem of the low, mean, and starving condition such are in who are under the law, and seek for happiness by the works of it:

and gave it unto Hagar, putting it on her shoulder; that is, the bread and the water, which might be put in one parcel or bundle, or in a basket, and so laid and carried on her shoulder: the Targum of Jonathan adds,"and bound it to her loins, to show that she was an handmaid:"

and the child; not that the child was "on her shoulder", which is quite improbable; for, since he was thirteen years of age when he was circumcised, he must be fourteen when Isaac was born; and if Isaac was two years old when weaned, Ishmael must be sixteen; and if he was three years of age, he must be seventeen; and if five years, he must be nineteen: some of the Jewish writers say (z), he was twenty seven years of age when he went out of his father's house; but they seem to come nearest the truth that make this event to be when he was at the age of seventeen (a), and when he must be too big to be carried on his mother's shoulder: but the sense is, that Abraham, when he put the provision on her shoulder, gave Ishmael to her, delivered him into her hand, to be taken care of by her; and very probably she led him in her hand:

and sent her away out of his house to some place assigned for her; the Targum of Jonathan adds, with a bill of divorce, dismissing her not only from his house, but as his wife; and so the Jewish writers (b) generally understand it: but there is no reason to believe there was any such custom before the law of Moses: nay, they go further, and say, that he dismissed her from himself, and from Isaac his son, and from this world, and from the world to come:

and she departed, and wandered in the wilderness of Beersheba; or, as the Targum of Jonathan, in the wilderness which was near to Beersheba; the place where it is probable Abraham now lived, and where Isaac was born, and the above affair was transacted, which was afterwards called by this name; for this is said by way of anticipation, see Gen 21:31. Beersheba is said (c) to be twelve miles from Gerar, and twenty miles from Hebron, to the south (d).
