The dismissal of Hagar and Ishmael. "The son of Hagar ... laughing." The birth of Isaac has made a great change in the position of Ishmael, now at the age of at least fifteen years. He was not now, as formerly, the chief object of attention, and some bitterness of feeling may have arisen on this account. His laugh was therefore the laugh of derision. Rightly was the child of promise named Isaac, the one at whom all laugh with various feelings of incredulity, wonder, gladness, and scorn. Sarah cannot brook the insolence of Ishmael, and demands his dismissal. This was painful to Abraham. Nevertheless, God enjoins it as reasonable, on the ground that in Isaac was his seed to be called. This means not only that Isaac was to be called his seed, but in Isaac as the progenitor was included the seed of Abraham in the highest and utmost sense of the phrase. From him the holy seed was to spring that was to be the agent in eventually bringing the whole race again under the covenant of Noah, in that higher form which it assumes in the New Testament. Abraham is comforted in this separation with a renewal of the promise concerning Ishmael Genesis 17:20.

He proceeds with all singleness of heart and denial of self to dismiss the mother and the son. This separation from the family of Abraham was, no doubt, distressing to the feelings of the parties concerned. But it involved no material hardship to those who departed, and conferred certain real advantages. Hagar obtained her freedom. Ishmael, though called a lad, was at an age when it is not unusual in the East to marry and provide for oneself. And their departure did not imply their exclusion from the privileges of communion with God, as they might still be under the covenant with Abraham, since Ishmael had been circumcised, and, at all events, were under the broader covenant of Noah. It was only their own voluntary rejection of God and his mercy, whether before or after their departure, that could cut them off from the promise of eternal life. It seems likely that Hagar and Ishmael had so behaved as to deserve their dismissal from the sacred home. "A bottle of water."

This was probably a kid-skin bottle, as Hagar could not have carried a goat-skin. Its contents were precious in the wilderness, but soon exhausted. "And the lad." He took the lad and gave him to Hagar. The bread and water-skin were on her shoulder; the lad she held by the hand. "In the wilderness of Beer-sheba." It is possible that the departure of Hagar occurred after the league with Abimelek and the naming of Beer-sheba, though coming in here naturally as the sequel of the birth and weaning of Isaac. The wilderness in Scripture is simply the land not profitable for cultivation, though fit for pasture to a greater or less extent. The wilderness of Beer-sheba is that part of the wilderness which was adjacent to Beer-sheba, where probably at this time Abraham was residing. "Laid the lad." Ishmael was now, no doubt, thoroughly humbled as well as wearied, and therefore passive under his mother's guidance. She led him to a sheltering bush, and caused him to lie down in its shade, resigning herself to despair. The artless description here is deeply affecting.

Mocking - What was implied in this mocking is not known. St. Paul, Galatians 4:29, calls it persecuting; but it is likely he meant no more than some species of ridicule used by Ishmael on the occasion, and probably with respect to the age of Sarah at Isaac's birth, and her previous barrenness. Jonathan ben Uzziel and the Jerusalem Targum represent Ishmael as performing some idolatrous rite on the occasion, and that this had given the offense to Sarah. Conjectures are as useless as they are endless. Whatever it was, it became the occasion of the expulsion of himself and mother. Several authors are of opinion that the Egyptian bondage of four hundred years, mentioned Genesis 15:13, commenced with this persecution of the righteous seed by the son of an Egyptian woman.

And Sarah saw the son of Hagar the Egyptian,.... That is, Ishmael, who is not expressed by name, but described by being a son of Hagar, a servant of Sarah's, and an Egyptian woman; all which seems to be observed by way of slight, both to Hagar and her son:

which she had born unto Abraham; not unto Sarah, as she proposed to herself, when she gave her maid to Abraham, Genesis 16:2. This son of Abraham she saw

mocking; either at the entertainment made at the weaning of Isaac; or rather at Isaac himself, laughing at his name, and treating him with contempt as his younger brother, and boasting that he was the firstborn, and that the inheritance belonged to him; and threatening what he would do to him, should he hereafter offer to dispute it with him, under pretence of the promise of God that he should be Abraham's heir, and at which promise also he may be supposed to mock: and that this contention was about the inheritance seems plain from the words of Sarah in Genesis 21:10; and in it Ishmael might not only rise to high words, but come to blows, and beat his brother; for it is observed the word used sometimes so signifies, 2 Samuel 2:14; wherefore the apostle might truly call it a persecution, Galatians 4:29; and as even cruel mockings are, Hebrews 11:35. As for the various senses the Jewish commentators put upon this, there does not seem to be any foundation for them, as that Ishmael was committing idolatry, and endeavouring to draw his brother into it; or was talking in an indecent and lascivious manner, in order to corrupt his mind; or that he was intending and attempting to take away his life, by shooting an arrow at him, and pretending it was but in jest and in play; See Gill on Galatians 4:29.

Sarah therefore asked that the maid and her son might be sent away, saying, the latter "shall not be heir with Isaac." The demand, which apparently proceeded from maternal jealousy, displeased Abraham greatly "because of his son," - partly because in Ishmael he loved his own flesh and blood, and partly on account of the promise received for him (Genesis 17:18 and Genesis 17:20). But God (Elohim, since there is no appearance mentioned, but the divine will was made known to him inwardly) commanded him to comply with Sarah's demand: "for in Isaac shall seed (posterity) be called to thee." This expression cannot mean "thy descendants will call themselves after Isaac," for in that case, at all events, זרעך would be used; for "in (through) Isaac shall seed be called into existence to thee," for קרא does not mean to call into existence; but, "in the person of Isaac shall there be posterity to thee, which shall pass as such," for נקרא includes existence and the recognition of existence. Though the noun is not defined by any article, the seed intended must be that to which all the promises of God referred, and with which God would establish His covenant (Genesis 17:21, cf. Romans 9:7-8; Hebrews 11:18). To make the dismissal of Ishmael easier to the paternal heart, God repeated to Abraham (Genesis 21:13) the promise already given him with regard to this son (Genesis 17:20).

And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, {c} mocking.

(c) He derided God's promise made to Isaac which the apostle calls persecution Ga 4:29.

21:9 Sarah saw the son of the Egyptian mocking - Mocking Isaac no doubt, for it is sad, 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 four hundred years affliction of the seed of Abraham by the Egyptians began now, and was to be dated from hence.

9. Sarah saw the son of Hagar . mocking-Ishmael was aware of the great change in his prospects, and under the impulse of irritated or resentful feelings, in which he was probably joined by his mother, treated the young heir with derision and probably some violence (Ga 4:29).

21:9-13 Let us not overlook the manner in which this family matter instructs us not to rest in outward privileges, or in our own doings. And let us seek the blessings of the new covenant by faith in its Divine Surety. Ishmael's conduct was persecution, being done in profane contempt of the covenant and promise, and with malice against Isaac. 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. Mocking is a great sin, and very provoking to God. And the children of promise must expect to be mocked. Abraham was grieved that Ishmael should misbehave, and Sarah demand so severe a punishment. But God showed him that Isaac must be the father of the promised Seed; therefore, send Ishmael away, lest he corrupt the manners, or try to take the rights of Isaac. The covenant seed of Abraham must be a people by themselves, not mingled with those who were out of covenant: Sarah little thought of this; but God turned aright what she said.
