12. Then Isaac sowed. Here Moses proceeds to relate in what manner Isaac reaped the manifest fruit of the blessing promised to him by God; for he says, that when he had sowed, the increase was a hundredfold: which was an extraordinary fertility, even in that land. He also adds, that he was rich in cattle, and had a very great household. Moreover, he ascribes the praise of all these things to the blessing of God; as it is also declared in the psalm, that the Lord abundantly supplies what will satisfy his people while they sleep. (Psalm 127:2.) It may, however, be asked, how could Isaac sow when God had commanded him to be a stranger all his life? Some suppose that he had bought a field, and so translate the word קנה (kanah) a possession; but the context corrects their error: for we find soon afterwards, that the holy man was not delayed, by having land to sell, from removing his effects elsewhere: besides, since the purchasing of land was contrary to his peculiar vocation and to the command of God, Moses undoubtedly would not have passed over such a notable offense. To this may be added, that since express mention is immediately made of a tent, we may hence infer, that wherever he might come, he would have to dwell in the precarious condition of a stranger. We must, therefore, maintain, that he sowed in a hired field. For although he had not a foot of land in his own possession, yet, that he might discharge the duty of a good householder, it behaved him to prepare food for his family; and perhaps hunger quickened his care and industry, that he might with the greater diligence make provision for himself against the future. Nevertheless, it is right to keep in mind, what I have lately alluded to, that he received as a divine favor the abundance which he had acquired by his own labor.

14. And the Philistines envied him. We are taught by this history that the blessings of God which pertain to the present earthly life are never pure and perfect, but are mixed with some troubles, lest quiet and indulgence should render us negligent. Wherefore, let us all learn not too ardently to desire great wealth. If the rich are harassed by any cause of disquietude, let them know that they are roused by the Lord, lest they should fall fast asleep in the midst of their pleasures; and let the poor enjoy this consolation, that their poverty is not without its advantages. For it is no light good to live free from envy, tumults, and strifes. Should any one raise the objection, that it can by no means be regarded as a favor, that God, in causing Isaac to abound in wealth, exposed him to envy, to contentions, and to many troubles; there is a ready answer, that not all the troubles with which God exercises his people, in any degree prevent the benefits which he bestows upon them from retaining the taste of his paternal love. Finally, he so attempers the favor which he manifests towards his children in this world, that he stirs them up, as with sharp goads, to the consideration of a celestial life. It was not, however, a slight trial, that the simple element of water, which is the common property of all animals, was denied to the holy patriarch; with how much greater patience ought we to bear our less grievous sufferings! If, however, at any time we are angry at being unworthily injured; let us remember that, at least, we are not so cruelly treated as holy Isaac was, when he had to contend for water. Besides, not only was he deprived of the element of water, but the wells which his father Abraham had dug for himself and his posterity were filled up. This, therefore, was the extreme of cruelty, not only to defraud a stranger of every service due to him, but even to take from him what had been obtained by the labor of his own father, and what he possessed without inconvenience to any one.

16. And Abimelech said unto Isaac. It is uncertain whether the king of Gerar expelled Isaac of his own accord from his kingdom, or whether he commanded him to settle elsewhere, because he perceived him to be envied by the people. He possibly might, in this manner, advise him as a friend; although it is more probable that his mind had become alienated from Isaac; for at the close of the chapter Moses relates, that the holy man complains strongly of the king as well as of others. But since we can assert nothing with certainty respecting the real feelings of the lying, let it suffice to maintain, what is of more importance, that in consequence of the common wickedness of mankind, they who are the most eminent fall under the suspicion of the common people. Satiety, indeed, produces ferocity. Wherefore there is nothing to which the rich are more prone than proudly to boast, to carry themselves more insolently than they ought, and to stretch every nerve of their power to oppress others. No such suspicion, indeed, could fall upon Isaac; but he had to bear that envy which was the attendant on a common vice. Whence we infer, how much more useful and desirable it often is, for us to be placed in a moderate condition; which is, at least, more peaceful, and which is neither exposed to the storms of envy, nor obnoxious to unjust suspicions. Moreover, how rare and unwonted was the blessing of God in rendering Isaac prosperous, may be inferred from the fact, that his wealth had become formidable both to the king and to the people. A large inheritance truly had descended to him from his father; but Moses shows, that from his first entrance into the land, he had so greatly prospered in a very short time, that it seemed no longer possible for the inhabitants to endure him.

18. And Isaac digged again the wells of water. First, we see that the holy man was so hated by his neighbors, as to be under the necessity of seeking a retreat for himself which was destitute of water; and no habitation is so troublesome and inconvenient for the ordinary purposes of life as that which suffers from scarcity of water. Besides, the abundance of his cattle and the multitude of his servants — who were like a little army — rendered a supply of water very necessary; whence we learn that he was brought into severe straits. But that this last necessity did not instigate him to seek revenge, is a proof of singular forbearance; for we know that lighter injuries will often rack the patience even of humane and moderate men. If any one should object to this view, that he was deficient in strength; I grant, indeed, that he was not able to undertake a regular war; but as his father Abraham had armed four hundred servants, he also certainly had a large troop of domestics, who could easily have repelled any force brought against him by his neighbors. But the hope which he had entertained when he settled in the valley of Gerar, was again suddenly cut off. He knew that his father Abraham had there used wells which were his own, and which he had himself discovered; and although they had been stopped up, yet they were well known to have sufficient springs of water to prevent the labor of digging them again from being misspent. Moreover, the fact that the wells had been obstructed ever since the departure of Abraham, shows how little respect the inhabitants had for their guest; for although their own country would have been benefited by these wells, they chose rather to deprive themselves of this advantage than to have Abraham for a neighbor; for, in order that such a convenience might not attract him to the place, they, by stopping up the wells, did, in a certain sense, intercept his way. It was a custom among the ancients, if they wished to involve any one in ruin, and to cut him off from the society of men, to interdict him from water, and from fire: thus the Philistine, for the purpose of removing Abraham from their vicinity, deprive him of the element of water.

He called their names. He did not give new names to the wells, but restored those which had been assigned them by his father Abraham, that, by this memorial, the ancient possession of them might be renewed. But subsequent violence compelled him to change their names, that at least he might, by some monument, make manifest the injury which had been done by the Philistines, and reprove them on account of it: for whereas he calls one well strife, or contention, another hostility, he denies that the inhabitants possessed that by right, or by any honest title, which they had seized upon as enemies or robbers. Meanwhile, it is right to consider, that in the midst of these strifes he had a contest not less severe with thirst and deficiency of water, whereby the Philistines attempted to destroy him; such is the scope of the history. First, Moses, according to his manner, briefly runs through the summary of the affair: namely, that Isaac intended to apply again to his own purpose the wells which his father had previously found, and to acquire, in the way of recovery, the lost possession of them. He then prosecutes the subject more diffusely, stating that, when he attempted the work, he was unjustly defrauded of his labor; and whereas, in digging the third well, he gives thanks to God, and calls it Room,³⁹³⁹     Latitudines, a literal Latin translation of the Hebrew word רהבת (Rehoboth,) a plural form, expressing the notion of abundant enlargement and room. — Ed because, by the favor of God, a more copious supply is now afforded him, he furnishes an example of invincible patience. Therefore, however severely he may have been harassed, yet when, after he had been freed from these troubles, he so placidly returns thanks to God, and celebrates his goodness, he shows that in the midst of trials he has retained a composed and tranquil mind.

23. And he went up from thence to Beer-sheba. Next follows a more abundant consolation, and one affording effectual refreshment to the mind of the holy man. In the tranquil enjoyment of the well, he acknowledges the favor which God had showed him: but forasmuch as one word of God weighs more with the faithful than the accumulated mass of all good things, we cannot doubt that Isaac received this oracle more joyfully than if a thousand rivers of nectar had flowed unto him: and truly Moses designedly commemorates in lofty terms this act of favor, that the Lord encouraged him by his own word, (Genesis 26:24;) whence we may learn, in ascribing proper honor to each of the other gifts of God, still always to give the palm to that proof of his paternal love which he grants us in his word. Food, clothing, health, peace, and other advantages, afford us a taste of the Divine goodness; but when he addresses us familiarly, and expressly declares himself to be our Father, then indeed it is that he thoroughly refreshes us to satiety. Moses does not explain what had been the cause of Isaac’s removal to Beer-sheba, the ancient dwelling-place of his fathers. It might be that the Philistines ceased not occasionally to annoy him; and thus the holy man, worn out with their implacable malice, removed to a greater distance. It is indeed probable, taking the circumstance of the time into account, that he was sorrowful and anxious; for as soon as he had arrived at that place, God appeared unto him on the very first night. Here, then, something very opportune is noticed. Moreover, as often as Moses before related that God had appeared unto Abraham, he, at the same time, showed that the holy man was either tormented with grievous cares, or was held in suspense under some apprehension, or was plunged in sadness, or, after many distresses, was nearly borne down by fatigue, so as to render it apparent that the hand of God was seasonably stretched out to him as his necessity required, lest he should sink under the evils which surrounded him. So now, as I explain it, he came to Isaac, for the purpose of restoring him, already wearied and broken down by various miseries.

24. And the Lord appeared unto him. This vision (as I have elsewhere said) was to prepare him to listen more attentively to God, and to convince him that it was God with whom he had to deal; for a voice alone would have had less energy. Therefore God appears, in order to produce confidence in and reverence towards his word. In short, visions were a kind of symbols of the Divine presence, designed to remove all doubt from the minds of the holy fathers respecting him who was about to speak. Should it be objected, that such evidence was not sufficiently sure, since Satan often deceives men by similar manifestations, being, as it were, the ape of God; — we must keep in mind what has been said before, that a clear and unambiguous mark was engraven on the visions of God, by which the faithful might certainly distinguish them from those which were fallacious, so that their faith should not be kept in suspense: and certainly, since Satan can only delude us in the dark, God exempts his children from this danger, by illuminating their eyes with the brightness of his countenance. Yet God did not fully manifest his glory to the holy fathers, but assumed a form by means of which they might apprehend him according to the measure of their capacities; for, as the majesty of God is infinite, it cannot be comprehended by the human mind, and by its magnitude it absorbs the whole world. Besides, it follows of necessity that men, on account of their infirmity, must not only faint, but be altogether annihilated in the presence of God. Wherefore, Moses does not mean that God was seen in his true nature and greatness, but in such a manner as Isaac was able to bear the sight. But what we have said, namely, that the vision was a testimony of Deity, for the purpose of giving credibility to the oracle, will more fully appear from the context; for this appearance was not a mute spectre; but the word immediately followed, which confirmed, in the mind of Isaac, faith in gratuitous adoption and salvation.

I am the God of Abraham. This preface is intended to renew the memory of all the promises before given, and to direct the mind of Isaac to the perpetual covenant which had been made with Abraham, and which was to be transmitted, as by tradition, to his posterity. The Lord therefore begins by declaring himself to be the God who had spoken at the first to Abraham, in order that Isaac might not sever the present from the former oracles: for as often as he repeated the testimony of his grace to the faithful, he sustained their faith with fresh supports. Yet he would have that very faith to remain based upon the first covenant by which he had adopted them to himself: and we must always keep this method in mind, in order that we may learn to gather together the promises of God, as they are combined in an inseparable bond. Let this also ever occur to us, as a first principle, that God thus kindly promises us his grace because he has freely adopted us.

Fear not. Since these words are elsewhere expounded, I shall now be the more brief. In the first place, we must observe, that God thus addresses the faithful for the purpose of tranquillizing their minds; for, if his word be withdrawn, they necessarily become torpid through stupidity, or are tormented with disquietude. Whence it follows, that we can receive peace from no other source than from the mouth of the Lord, when he declares himself the author of our salvation; not that we are then free from all fear, but because the confidence of faith is sufficiently efficacious to assuage our perturbations. Afterwards the Lord gives proofs of his love, by its effect, when he promises that he will bless Isaac.
