Verses 1-34

ISHMAEL AND ISAAC

Genesis 21:1-34; Genesis 22:1-24

Abraham had two sons, the one by a bondmaid, the other by a freewoman. Which things are an allegory.- Galatians 4:22.

"Abraham stretched forth his hand, and took the knife to slay his son." Genesis 22:10

IN the birth of Isaac, Abraham at length sees the long-delayed fulfilment of the promise. But his trials are by no means over. He has himself introduced into his family the seeds of discord and disturbance, and speedily the fruit is borne. Ishmael, at the birth of Isaac, was a lad of fourteen years, and, reckoning from Eastern customs, he must have been over sixteen when the feast was made in honour of the weaned child. Certainly he was quite old enough to understand the important and not very welcome alteration in his prospects which the birth of this new son effected. He had been brought up to count himself the heir of all the wealth and influence of Abraham. There was no alienation of feeling between father and son: no shadow had flitted over the bright prospect of the boy as he grew up; when suddenly and unexpectedly there was interposed between him and his expectation the effectual barrier of this child of Sarah’s. The importance of this child to the family was in due course indicated in many ways offensive to Ishmael; and when the feast was made, his spleen could no longer be repressed. This weaning was the first step in the direction of an independent existence, and this would be the point of the feast in celebration. The child was no longer a mere part of the mother, but an individual, a member of the family. The hopes of the parents were carried forward to the time when he should be quite independent of them.

But in all this there was great food for the ridicule of a thoughtless lad. It was precisely the kind of thing which could easily be mocked without any great expenditure of wit by a boy of Ishmael’s age. The too visible pride of the aged mother, the incongruity of maternal duties with ninety years, the concentration of attention and honours on so small an object, -all this was, doubtless, a temptation to a boy who had probably at no time too much reverence. But the words and gestures which others might have disregarded as childish frolic, or, at worst, as the unseemly and ill-natured impertinence of a boy who knew no better, stung Sarah, and left a poison in her blood that infuriated her. "Cast out that bondwoman and her son," she demanded of Abraham. Evidently she feared the rivalry of this second household of Abraham, and was resolved it should come to an end. The mocking of Ishmael is but the violent concussion that at last produces the explosion, for which material has long been laid in train. She had seen on Abraham’s part a clinging to Ishmael, which she was unable to appreciate. And though her harsh decision was nothing more than the dictate of maternal jealousy, it did prevent things from running on as they were until even a more painful family quarrel must have been the issue.

The act of expulsion was itself unaccountably harsh. There was nothing to prevent Abraham sending the boy and his mother under an escort to some safe place; nothing to prevent him from giving the lad some share of his possessions sufficient to provide for him. Nothing of this kind was done. The woman and the boy were simply put to the door; and this, although Ishmael had for years been counted Abraham’s heir, and though he was a member of the covenant made with Abraham. There may have been some law giving Sarah absolute power over her maid; but if any law gave her power to do what was now done, it was a thoroughly barbarous one, and she was a barbarous woman who used it.

It is one of those painful cases in which one poor creature clothed with a little brief authority stretches it to the utmost in vindictive maltreatment of another. Sarah happened to be mistress, and, instead of using her position to make those under her happy, she used it for her own convenience, for the gratification of her own spite, and to make those beneath her conscious of her power by their suffering. She happened to be a mother, and instead of bringing her into sympathy with all women and their children, this concentrated her affection with a fierce jealousy on her own child. She breathed freely when Hagar and Ishmael were fairly out of sight. A smile of satisfied malice betrayed her bitter spirit. No thought of the sufferings to which she had committed a woman who had served her well for years, who had yielded everything to her will, and who had no other natural protector but her, no glimpses of Abraham’s saddened face, visited her with any relentings. It mattered not to her what came of the woman and the boy to whom she really owed a more loving and careful regard than to any except Abraham and Isaac. It is a story often repeated. One who has been a member of the household for many years is at last dismissed at the dictate of some petty pique or spite as remorselessly and inhumanly as a piece of old furniture might be parted with. Some thoroughly good servant, who has made sacrifices to forward his employer’s interest, is at last. through no offence of his own, found to be in his employer’s way, and at once all old services are forgotten, all old ties broken, and the authority of the employer, legal but inhuman, is exercised. It is often those who can least defend themselves who are thus treated; no resistance is possible, and also, alas! the party is too weak to face the wilderness on which she is thrown out, and if any cares to follow her history, we may find her at the last gasp under a bush.

Still, both for Abraham and for Ishmael, it was better this severance should take place. It was grievous to Abraham; and Sarah saw that for this very reason it was necessary. Ishmael was his firstborn, and for many years had received the whole of his parental affection: and, looking on the little Isaac, he might feel the desirableness of keeping another son in reserve, lest this strangely-given child might as strangely pass away. Coming to him in a way so unusual, and having perhaps in his appearance some indication of his peculiar birth, he might seem scarcely fit for the rough life Abraham himself had led. On the other hand, it was plain that in Ishmael were the very qualities which Isaac was already showing that he lacked. Already Abraham was observing that with all his insolence and turbulence there was a natural force and independence of character which might come to be most useful in the patriarchal household. The man who had pursued and routed the allied kings could not but be drawn to a youth who already gave promise of capacity for similar enterprises-and this youth his own son. But can Abraham have failed to let his fancy picture the deeds this lad might one day do at the head of his armed slaves? And may he not have dreamt of a glory in the land not altogether such as the promise of God encouraged him to look for, but such as the tribes around would acknowledge and fear? All the hopes Abraham had of Ishmael had gained firm hold of his mind before Isaac was born; and before Isaac grew up, Ishmael must have taken the most influential place in the house and plans of Abraham. His mind would thus have received a strong bias towards conquests and forcible modes of advance. He might have been led to neglect, and, perhaps, finally despise, the unostentatious blessings of heaven.

If, then, Abraham was to become the founder, not of one new warlike power in addition to the already too numerous warlike powers of the East, but of a religion which should finally develop into the most elevating and purifying influence among men, it is obvious that Ishmael was not at all a desirable heir. Whatever pain it gave to Abraham to part with him, separation in some form had become necessary. It was impossible that the father should continue to enjoy the filial affection of Ishmael, his lively talk, and warm enthusiasm, and adventurous exploits, and at the same time concentrate his hope and his care on Isaac. He had, therefore, to give up, with something of the sorrow and self-control he afterwards underwent in connection with the sacrifice of Isaac, the lad whose bright face had for so many years shone in all his paths. And in some such way are we often called to part with prospects which have wrought themselves very deep into our spirit, and which, indeed, just because they are very promising and seductive, have become dangerous to us, upsetting the balance of our life, and throwing into the shade objects and purposes which ought to be outstanding. And when we are thus required to give up what we were looking to for comfort, for applause, and for profit, the voice of God in its first admonition sometimes seems to us little better than the jealousy of a woman. Like Sarah’s demand, that none should share with her son, does the requirement seem which indicates to us that we must set nothing on a level with God’s direct gifts to us. We refuse to see why we may not have all the pleasures and enjoyments, all the display and brilliance that the world can give. We feel as if we were needlessly restricted. But this instance shows us that when circumstances compel us to give up something of this kind which we have been cherishing, room is given for a better thing than itself to grow.

For Ishmael himself, too, wronged as he was in the mode of his expulsion, it was yet far better that he should go. Isaac was the true heir. No jeering allusions to his late birth or to his appearance could alter that fact. And to a temper like Ishmael’s it was impossible to occupy a subordinate, dependent position. All he required to call out his latent powers was to be thrown thus on his own resources. The daring and high spirit and quickness to take offence and use violence, which would have wrought untold mischief in a pastoral camp, were the very qualities which found fit exercise in the desert, and seemed there only in keeping with the life he had to lead. And his hard experience at first would at his age do him no harm, but good only. To be compelled to face life single-handed at the age of sixteen is by no means a fate to be pitied. It was the making Of Ishmael. and is the making of many a lad in every generation.

But the two fugitives are soon reminded that, though expelled from Abraham’s tents and protection, they are not expelled from his God. Ishmael finds it true that when father and mother forsake him, the Lord takes him up. At the very outset of his desert life he is made conscious that God is still his God, mindful of his wants, responsive to his cry of distress.

It was not through Ishmael the promised seed was to come, but the descendants of Ishmael had every inducement to retain faith in the God of Abraham, who listened to their father’s cry. The fact of being excluded from certain privileges did not involve that they were to be excluded from all privileges. God still "heard the voice of the lad, and the angel of God called to Hagar out of heaven."

It is this voice of God to Hagar that so speedily, and apparently once for all, lifts her out of despair to cheerful hope. It would appear as if her despair had been needless; at least from the words addressed to her, "What aileth thee, Hagar?" it would appear as if she might herself have found the water that was close at hand, if only she had been disposed to look for it. But she had lost heart, and perhaps with her despair was mingled some resentment, not only at Sarah, but at the whole Hebrew connection, including the God of the Hebrews, who had before encouraged her. Here was the end of the magnificent promise which that God had made her before her child was born-a helpless human form gasping its life away without a drop of water to moisten the parched tongue and bring light to the glazing eyes, and with no easier couch than the burning sand. Was it for this, the bitterest drop that, apart from sin, can be given to any parent to drink, she had been brought from Egypt and led through all her past? Had her hopes been nursed by means so extraordinary only that they might be so bitterly blighted? Thus she learnt to her conclusions, and judged that because her skin of water had failed God had failed her too. No one can blame her, with her boy dying before her, and herself helpless to relieve one pang of his suffering. Hitherto, in the well-furnished tents of Abraham, she had been able to respond to his slightest desire. Thirst he had never known, save as the relish to some boyish adventure. But now, when his eyes appeal to her in dying anguish, she can but turn away in helpless despair. She cannot relieve his simplest want. Not for her own fate has she any tears, but to see her pride, her life and joy, perishing thus miserably, is more than she can bear.

No one can blame, but every one may learn from her. When angry resentment and unbelieving despair fill the mind, we may perish of thirst in the midst of springs. When God’s promises produce no faith, but seem to us so much waste paper, we are necessarily in danger of missing their fulfilment. When we ascribe to God the harshness and wickedness of those who represent Him in the world, we commit moral suicide. So far from the promises given to Hagar being now at the point of extinction, this was the first considerable step toward their fulfilment. When Ishmael turned his back on the familiar tents, and flung his last gibe at Sarah, he was really setting out to a far richer inheritance, so far as this world goes, than ever fell to Isaac and his sons.

But the chief use Paul makes of this entire episode in the history is to see in it an allegory. a kind of picture made up of real persons and events, representing the impossibility of law and gospel living harmoniously together, the incompatibility of a spirit of service with a spirit of sonship. Hagar, he says, is in this picture the likeness of the law given from Sinai, which gendereth to bondage. Hagar and her son, that is to say, stand for the law and the kind of righteousness produced by the law, -not superficially a bad kind; on the contrary, a righteousness with much dash and brilliance and strong manly force about it. but at the root defective, faulty in its origin, springing from the slavish spirit. And first Paul bids us notice how the free-born is persecuted and mocked by the slave-born, that is, how the children of God who are trying to live by love and faith in Christ are put to shame and made uneasy by the law. They believe they are God’s dear children, that they are loved by Him, and may go out and in freely in His house as their own home, using all that is His with the freedom of His heirs; but the law mocks them, frightens them, tells them it is God’s firstborn; law lying far back in the dimness of eternity, coeval with God Himself. It tells them they are puny and weak, scarcely out of their mother’s arms, tottering, lisping creatures, doing much mischief, but none of the housework, at best only getting some little thing to pretend to work at. In contrast to their feeble, soft, unskilled weakness, it sets before them a finely-moulded, athletic form, becoming disciplined to all work, and able to take a place among the serviceable and able-bodied. But with all this there is in that puny babe a life begun which will grow and make it the true heir, dwelling in the house and possessing what it has not toiled for, while the vigorous, likely-looking lad must go into the wilderness and make a possession for himself with his own bow and spear.

Now, of course, righteousness of life and character, or perfect manhood, is the end at which all that we call salvation aims, and that which can give us the purest, ripest character is salvation for us; that which can make us, for all purposes, most serviceable and strong. And when we are confronted with persons who might speak of service we cannot render, of an upright, unfaltering carriage we cannot assume, of a general human worthiness we can make no pretension to, we are justly perturbed, and should regain our equanimity only under the influence of the most undoubted truth-and fact. If we can honestly say in our hearts, "Although we can show no such work done, and no such masculine growth, yet we have a life in us which is of God, and will grow"; if we are sure that we have the spirit of God’s children, a spirit of love and dutifulness, we may take comfort from this incident. We may remind ourselves that it is not he who has at the present moment the best appearance who always abides in the father’s home, but he who is by birth the heir. Have we or have we not the spirit of the Son? not feeling that we must every evening make good our claim to another night’s lodging by showing the task we have. accomplished, but being conscious that the interests in which we are called to work are our own interests, that we are heirs in the father’s house, so that all we do for the house is really done for ourselves. Do we go out and in with God, feeling no need of His commands, our own eye seeing where help is required, and our own desires being wholly directed towards that which engages all His attention and work?

For Paul would have each of us apply, allegorically, the words, Cast out the bondwoman and her son, that is, cast out the legal mode of earning a standing in God’s house, and with this legal mode cast out all the self-seeking, the servile fear of God, the self-righteousness, and the hardheartedness it engenders. Cast out wholly from yourself the spirit of the slave, and cherish the spirit-of the son and heir. The slave-born may seem for a while to have a firm footing in the father’s house, but it cannot last. The temper and tastes of Ishmael are radically different from those of Abraham, and when the slave-born becomes mature, the wild Egyptian strain will appear in his character. Moreover, he looks upon the goods of Abraham as plunder; he cannot rid himself of the feeling of an alien, and this would, at length, show itself in a want of frankness with Abraham-slowly, but surely, the confidence between them would be worn out. Nothing but being a child of God, being born of the Spirit, can give the feeling of intimacy, confidence, unity of interest, which constitutes true religion. All we do as slaves goes for nothing; that is to say, all we do, not because we see the good of it, but because we are commanded; not because we have any liking for the thing done, but because we wish to be paid for it. The day is coming when we shall attain our majority, when it will be said to us by God, Now, do whatever you like, whatever you have a mind to; no surveillance, no commands are now needed; I put all into your own hand. What, in these circumstances, should we straightway do? Should we, for the love of the thing, carry on the same work to which God’s commands had driven us; should we, if left absolutely in charge, find nothing more attractive than just to prosecute that idea of life and the world set before us by Christ? Or should we see that we had merely been keeping ourselves in check for a while, biding our time, untamed as Ishmael, craving the rewards but not the life of the children of God? The most serious of all questions these-questions that determine the issues of our whole life, that determine whether our home is to be-where all the best interests Of men and the highest blessings of God have their seat, or in the pathless desert where life is an aimless wandering, dissociated from all the forward movements of men.

The distinction between the servile spirit and the spirit of sonship being thus radical, it could be by no mere formality, or exhibition of his legal title, that Isaac became the heir of God’s heritage. His sacrifice on Moriah was the requisite condition of his succession to Abraham’s place; it was the only suitable celebration of his majority. Abraham himself had been able to enter into covenant with God only by sacrifice; and sacrifice not of a dead and external kind, but vivified by an actual surrender of himself to God, and by so true a perception of God’s holiness and requirements that he was in a horror of great darkness. By no other process can any of his heirs succeed to the inheritance. A true resignation of self, in whatever outward form this resignation may appear, is required that we may become one with God in His holy purposes and in His eternal blessedness. There could be no doubt that Abraham had found a true heir, when Isaac laid himself on the altar and steadied his heart to receive the knife. Dearer to God, and of immeasurably greater value than any service, was this surrender of himself into the hand of his Father and his God. In this was promise of all service and all loving fellowship. "Precious in the sight of the Lord is the death of His saints. O Lord, truly I am Thy servant; I am Thy servant, the son of Thine handmaid: Thou hast loosed my bonds."

So incomparable with the most distinguished service did this sacrifice of Isaac’s self appear, that the record of his active life seems to have had no interest to his contemporaries or successors. There was but this one thing to say of him. No more seemed needful. The sacrifice was indeed great, and worthy of commemoration. No act could so conclusively have shown that Isaac was thoroughly at one with God. He had much to live for; from his birth there hovered round him interests and hopes of the most exciting and flattering nature; a new kind of glory such as had not yet been attained on earth was to be attained, or, at any rate, approached in him. This glory was certain to be realised, being guaranteed by God’s promise, so that his hopes might launch out in the boldest confidence and give him the aspect and bearing of a king; while it was uncertain in the time and manner of its realisation, so that the most attractive mystery hung around his future.

Plainly his was a life worth entering on and living through; a life fit to engage and absorb a man’s whole desire, interest, and effort; a life such as might well make a man gird himself and resolve to play the man throughout, that so each part of it might reveal its secret to him, and that none of its wonder might be lost. It was a life which, above all others, seemed worth protecting from all injury and risk, and for which, no doubt, not a few of the homeborn servants in the patriarchal encampment would have gladly ventured their own. There have, indeed, been few, if any, lives of which it could so truly be said, The world cannot do without this-at all hazards and costs this must be cherished. And all this must have been even more obvious to its owner than to any one else, and must have begotten in him an unquestioning assurance, that he at least had a charmed life, and would live and see good days. Yet with whatever shock the command of God came upon him, there is no word of doubt or remonstrance or rebellion. He gave his life to Him who had first given it to him. And thus yielding himself to God, he entered into the inheritance, and became worthy to stand to all time the representative heir of God, as Abraham by his faith had become the father of the faithful.
