3. A voice crying in the wilderness. He follows out the subject which he had begun, and declares more explicitly that he will send to the people, though apparently ruined, ministers of consolation. At the same time he anticipates an objection which might have been brought forward. “You do indeed promise consolation, but where are the prophets? For we shall be ‘in a wilderness,’ and whence shall this consolation come to us?” He therefore testifies that “the wilderness” shall not hinder them from enjoying that consolation.

The wilderness is employed to denote metaphorically that desolation which then existed; though I do not deny that the Prophet alludes to the intermediate journey; ¹¹⁰¹¹⁰     “Au chemin d’entre Iudee et Babylone.” “To the road between Judea and Babylon.” for the roughness of the wilderness seemed to forbid their return. He promises, therefore, that although every road were shut up, and not a chink were open, the Lord will easily cleave a path through the most impassable tracts for himself and his people.

Prepare the way of Jehovah. Some connect the words “in the wilderness” with this clause, and explain it thus, “Prepare the way of Jehovah in the wilderness.” But the Prophet appears rather to represent a voice which shall gather together those who had wandered and had, as it were, been banished from the habitable globe. “Though you behold nothing but a frightful desert, yet this voice of consolation shall be heard from the mouth of the prophets.” These words relate to the hard bondage which they should undergo in Babylon.

But to whom is that voice addressed? Is it to believers? No, but to Cyrus, to the Persians, and to the Medes, who held that people in captivity. Having been alienated from obedience to God, they are constrained to deliver the people; and therefore they are enjoined to “prepare and pave the way,” that the people of God may be brought back to Judea; as if he had said, “Make passable what was impassable.” The power and efficacy of this prediction is thus held up for our applause; for when God invests his servants with authority to command men who were cruel and addicted to plunder, and who at that time were the conquerors of Babylon, to “prepare the way” for the return of his people, he means that nothing shall hinder the fulfillment of his promise, because he will employ them all as hired servants. Hence we obtain an excellent consolation, when we see that God makes use of irreligious men for our salvation, and employs all the creatures, when the case demands it, for that end.

A highway for our God. When it is said that the way shall be prepared not for the Jews, but for God himself, we have here a remarkable proof of his love towards us; for he applies to himself what related to the salvation of his chosen people. The Lord had nothing to do with walking, and had no need of a road; but he shews that we are so closely united to him that what is done on our account he reckons to be done to himself. This mode of expression is frequently employed elsewhere, as when it is said that God “went forth into battle with his anointed,” (Habakkuk 3:13,) and that “he rode through the midst of Egypt,” (Exodus 11:4,) and that he lifted up his standard and led his people through the wilderness. (Isaiah 63:13.)

This passage is quoted by the Evangelists, (Matthew 3:3; Mark 1:3; Luke 3:4,) and applied to John the Baptist, as if these things had been foretold concerning him, and not unjustly; for he held the highest rank among the messengers and heralds of our redemption, of which the deliverance from Babylon was only a type. And, indeed, at the time when the Church arose out of her wretched and miserable condition, her mean appearance bore a stronger resemblance than the Babylonish captivity to a “wilderness;” but God wished that they should see plainly, in the wilderness in which John taught, the image and likeness of that miserably ruinous condition by which the whole beauty of the Church was injured and almost destroyed. What is here described metaphorically by the Prophet was at that time actually fulfilled; for at an exceedingly disordered and ruinous crisis John lifted up the banner of joy. True, indeed, the same voice had been previously uttered by Daniel, Zechariah, and others; but the nearer the redemption approached, the more impressively could it be proclaimed by John, who also pointed out Christ with the finger. (John 1:29.) But because, in the midst of a nation which was ignorant and almost sunk in stupidity, there were few that sincerely grieved for their ruinous condition, John sought a wilderness, that the very sight of the place might arouse careless persons to hope and desire the promised deliverance. As to his denying that he was a Prophet, (John 1:21,) this depends on the end of his calling and the substance of his doctrine; for he was not sent to discharge apart any continued office, but, as a herald, to gain an audience for Christ his Master and Lord. What is here said about removing obstructions, he applies skilfully to individuals, on this ground, that the depravity of our nature, the windings of a crooked mind, and obstinacy of heart, shut up the way of the Lord, and hinder them from preparing, by true self-denial, to yield obedience.

4. Every valley shall be exalted. He confirms and asserts the preceding statement; for he shews that no difficulties can prevent the Lord from delivering and restoring his Church whenever he shall think fit. These words might with propriety be rendered in the imperative mood, “Let every valley be exalted,” ¹¹¹¹¹¹     “Grotius supposes the command at the beginning of the chapter to be still continued, (‘Let every valley, etc.,) and the latest German writers give the same construction of this verse, although they make a new command begin in the one preceding. The form of the following verb והיה, (vehayah,) though not incompatible with this explanation, rather favors the strict interpretation of the future, which is, of course, on general principles to be preferred.” — Alexander. so as to be placed in immediate connection with the command which God gives by his prophets to prepare and level the way for himself; but it makes hardly any difference in the meaning. Let us be satisfied with understanding the Prophet’s design, “that, although many and formidable difficulties are started to hinder the salvation of the Church, still the hand of God will be victorious and will prevail.”

And every mountain and hill shall be laid low. It ought to be observed that many obstructions always arise whenever God makes provision for our deliverance, or wishes to aid the afflicted; and although his glory is more fully displayed by these obstructions, yet we suffer no loss; for we behold more clearly his wonderful power when no strength, or efforts, or contrivances of men can prevent him from gaining his object. He conducts his people through “mountains” and steep places in such a manner as if the road were perfectly level; and by the words mountains and hills, the Prophet undoubtedly intends to denote metaphorically obstructions of every kind; for Satan attempts in every way to hinder our salvation. When we come, therefore, to spiritual redemption, these words undoubtedly include both internal and external obstacles, — lusts and wicked desires, ambition, foolish confidence, and impatience, which retard us wonderfully, but the Lord will break them all down; for when he stretches out his hand, nothing can restrain or drive him back.

5. And the glory of Jehovah shall be revealed. He means that this work of redemption will be splendid, so that the Lord will shew that he is the Author of it, and will illustriously display his majesty and power. This, indeed, is very openly manifested in all places and in all events, but he promises that he will do this especially in protecting and delivering his Church, and not without good reason; for the deliverance of the Church, from its commencement down to the coming of Christ, might be called a renewal of the world. ¹¹²¹¹²     “Un renonvellement incroyable, ou seconde creation du monde.” “An incredible renewal or second creation of the world.” And because the power of God, which he had formerly been accustomed to display, was almost extinguished, so that scarcely the slightest traces were discernible, as it is said in the Psalm, “We do not see our signs,” (Psalm 74:9;) this was a very seasonable warning, that a new and striking demonstration is promised, by which they may perceive that God has in his power various methods of giving relief, even when he conceals them for a time.

And all flesh shall see. He now heightens the miracle by an additional circumstance, that it will be known not only in Judea, but in foreign and distant countries; for by these words “All flesh shall see,” he means that there will be no nations that do not see clearly that the return of the people is a heavenly work, and that God did not speak in vain by the Prophet. Thus he censures the unbelief of men, who never rely on the promises of God, and who treat as fables whatever is said by the prophets, till by beholding the actual fact they are constrained to yield.

That the mouth of Jehovah hath spoken. Here we are taught what is the true method of correcting our unbelief; that is, to be employed in meditating on the promises of God, and to have our faith strengthened by all the proofs of them which he exhibits. Thus it is proper to join doctrine with experience; for since the sight of God’s works would produce little impression on us, he first enlightens us by the torch of his word, and next seals the truth of it by the actual accomplishment.

6. The voice said, Cry. He now describes a different “voice” from that of which he formerly spoke; for hitherto he had spoken about the “voice” of the prophets, but now he means the “voice” of God himself commanding the prophets to cry. Although the voice of the prophets is also the voice of God, whose instruments they are, (for they do not speak of themselves,) (2 Peter 1:20, 21,) yet this distinction is necessary, that we may know when the Lord commands, and when the prophets and ministers execute his commandments. There is also a beautiful comparison between the two “voices,” that we may receive with as much reverence what the prophets utter as if God himself thundered from heaven; for they speak only by his mouth, and repeat as ambassadors what he has commissioned them to declare. Besides, this preface gives notice that the Prophet is about to speak of something highly important; for, although he everywhere testifies that he faithfully delivers from hand to hand what he has received from God, yet, in order to obtain closer attention, he states that the voice of God has expressly enjoined the mode of speaking which he shall employ. Such is also the import of the word Cry, as if he had said that he must proclaim this commandment in a clear and loud voice, that it may make the deeper impression.

And I said, What shall I cry? The addition of this question has great weight; for the Prophet means that he does not break forth at random, and boast of what he appeared to have heard in a confused manner; but that he received clear and undoubted instruction, after having waited for it with composure. Besides, from the fact itself we may learn that there is nothing here that is superfluous, because two chief points of heavenly doctrine were to be briefly handled; that, although man is smoke and vanity, and all his excellence is deceitful and fading, yet believers have the best reason for glorying, because they seek salvation not from themselves; and that, although they are strangers on the earth, (Hebrews 11:13,) yet they possess heavenly happiness, because God unites himself to them by his word; for by renouncing ourselves we are led to desire the grace of God. The Prophet knew, indeed, what he ought to say; but by this question he intended to make a stronger impression on their minds, in order to shew that he and all the other servants of God are constrained by necessity to utter this sentiment, and that they cannot begin to teach in any other manner, though they should put a hundred questions and inquiries; as indeed they will gain nothing by choosing to adopt any other method.

As to the word Cry, I have no objection to view it as denoting both boldness and clearness; because prophets ought not to mutter in an obscure manner, but to pronounce their message with a distinct voice, and to utter boldly and with open mouth whatever they have been commanded to declare. Let every one, therefore, who is called to this office constantly remember and believe, that he ought to meet difficulties of every sort with unshaken boldness, such as was always manifested both by prophets and by apostles.

“Wo to me,” says Paul, “if I do not preach the gospel; for necessity is laid on me.”
(1 Corinthians 9:16.)

All flesh is grass. First, it ought to be observed, that he does not speak merely of the frailty of human life, but extends the discourse farther, so as to reduce to nothing all the excellence which men think that they possess. David indeed compares this life to grass, (Psalm 103:15,) because it is fading and transitory; but the context shews that the Prophet does not speak only of the outward man, but includes the gifts of the mind, of which men are exceedingly proud, such as prudence, courage, acuteness, judgment, skill in the transactions of business, in which they think that they excel other animals; and this is more fully expressed by that which immediately follows —

All the grace of it. Some translate חסדו (chasdo) “his glory;” others, “his kindness;” but I have preferred the word “grace,” by which I mean everything that procures honor and esteem to men. Yet a passive signification may also be admitted; as if the Prophet had said, that all that is excellent and worthy of applause among men is the absolute kindness of God. Thus David calls God “the God of his kindness,” (Psalm 59:10, 17,) because he acknowledges him to be the author of all blessings, and ascribes it to his grace that he has obtained them so largely and abundantly. It is indeed certain that חסד (chesed) here denotes all that is naturally most highly valued among men, and that the Prophet condemns it for vanity, because there is an implied contrast between the ordinary nature of mankind and the grace of regeneration.

Some commentators refer this to the Assyrians, as if the Prophet, by extenuating their power and wealth, and industry and exertions, or rather by treating these as they had no existence, freed the minds of the Jews from terror. They bring out the meaning in this manner, “If you are terrified at the strength of men, remember that they are flesh, which quickly gives way through its own weakness. But their error is soon afterwards refuted by the context, in which the Prophet expressly applies it to the Jews themselves. We ought carefully to observe that man, with his faculties, on account of which he is accustomed to value himself so highly, is wholly compared to a flower. All men are fully convinced of the frailty of human life, and on this subject heathen writers have argued at great length; but it is far more difficult to root out the confidence which men entertain through a false opinion of their wisdom; for, if they imagine that they have either knowledge or industry beyond others, they think that they have a right to glory in them. But he shews that in man there is nothing so excellent as not to fade quickly and perish.

As the flower of the field. The Prophet seems, as if in mockery, to add a sort of correction; for a flower is something more than grass. It is, therefore, an acknowledgment, that, although men have some shining qualities, like flowers in the fields, yet the beauty and lustre quickly vanish and pass away, so that it is useless for them to flatter or applaud themselves on account of this idle and deceitful splendor.

7. The grass is withered. This might be understood to relate to the beauty of the fields, which is spoiled by a single gust of wind, as it is said, (Psalm 103:16,) “As soon as the wind passeth over it, it is gone;” for we know that the wind is called “the Spirit of God” in other passages. But I am more inclined to think that the metaphor is adapted to the present subject; for otherwise the application of it would be somewhat obscure. The Prophet therefore explains what object he has in view, by saying that men, with all their glory, are nothing else than grass; theft is, because the Spirit of God will quickly carry them away by a single breath.

Because the Spirit of Jehovah hath blown upon it. The meaning may be thus explained, “However illustrious are the gifts with which men are endowed, yet as soon as the Spirit of God shall blow upon them, they shall feel that they are nothing.” For the false confidence with which they intoxicate themselves springs from this source, that they do not appear before God, but, in order to indulge freely in flattering themselves, creep into places of concealment. That they may no longer deceive themselves by a foolish delight in falsehood, the Prophet drags them into the presence of God, and admits that apparently they flourish, when they have been withdrawn from God; but as soon as the Lord has breathed upon them, all their strength and beauty perish and decay.

But it may be thought that he assigns to “the Spirit of God” an office which is greatly at variance with his nature; for it belongs to him “to renew by his power the face of the earth.” (Psalm 104:30.) On the other hand, if the Lord withdraw his Spirit, all is reduced to nothing. Here Isaiah asserts what is exceedingly different, and appears to contradict David. But there is no absurdity in saying that all things are renewed by the power of the Spirit, and again, that what formerly appeared to be something is reduced to nothing; for we are nothing but in God, and, in order that we may begin to be something in him, we must first be convinced, and made thoroughly to know, that we are vanity. Therefore does the Lord breathe upon us, that we may know that of ourselves we are nothing.

Surely the people is grass. The Prophet added this, that all might know that he was not speaking of foreigners, but of that people which gloried in the name of God; for the Jews might have thought that they were more excellent, and held a higher rank than other men, and that on this account they ought to be exempted from the common lot. He therefore addresses theta expressly and by name, that they may not claim anything for themselves above others; as if he had said, that they would act wisely if, through a conviction of their poverty, they should cast away all confidence in themselves. In a word, the Prophet, after having mentioned consolation, shews in what way men must be prepared to receive it; for they are not capable of it till they have formerly been reduced to nothing. Our hardness must therefore be softened, our haughtiness must be east down and laid low, our boasting must be put to shame, and our hearts must be subdued and humbled, if we wish to receive with any advantage the consolations which the prophets bring to us by the command of God.

8. The grass withereth. This repetition is again added for the purpose of bringing to nought the glory of the flesh, but at the same time contains within itself a highly valuable consolation, that God, when he has cast down his people, immediately raises up and restores them. The context therefore runs thus: “The grass indeed withereth and perisheth, but the word of the Lord endureth for ever.” After having learned how empty and destitute we are of all blessings, how transitory and fading is the glory of the flesh, the only consolation left for us, that we may be raised up by the word of the Lord, as by an outstretched hand, is, that we are frail and fading, but that the word of the Lord is durable and eternal, and, in a word, that the life which we need is offered to us from another quarter.

But the word of our God shall stand for ever. This passage comprehends the whole Gospel in few words; for it consists of an acknowledgment of our misery, poverty, and emptiness, that, being sincerely humbled, we may fly to God, by whom alone we shall be perfectly restored. Let not men therefore faint or be discouraged by the knowledge of their nakedness and emptiness; for the eternal word is exhibited to them by which they may be abundantly supported and upheld. We are likewise taught that we ought not to seek consolation from any other source than from eternity, which ought not to be sought anywhere else than in God; since nothing that is firm or durable will be found on the earth. Nothing is more foolish than to rest satisfied with the present state, which we see to be fleeting; and every man is mistaken who hopes to be able to obtain perfect happiness till he has ascended to God, whom the Scripture calls eternal, in order that we may know that life flows to us from him; and indeed he adopts us to be his children on this condition, to make us partakers of his immortality.

But this would be of no avail, if the manner of seeking him were not pointed out; and therefore he exhibits the word, from which we must not in any respect turn aside; for if we make the smallest departure from it, we shall be involved in strange labyrinths, and shall find no way of extricating ourselves. Now, the word is called eternal, not merely in itself, but in us; and this ought to be particularly observed, because otherwise we could obtain no consolation. And thus Peter, a faithful expounder of this passage, applies it to us, when he says that “we are regenerated by this incorruptible seed, that is,” says he, “by the word which is preached.” (1 Peter 1:23, 25.) Hence we infer, what I mentioned a little before, that life is prepared for the dead who shall come thirsting to the fountain that is exhibited to them; for the power which is hid in God is revealed to us by the word.

9. Ascend on the high mountain. He proceeds with the same subject; for the Lord, having formerly promised that he would give prophets who should soothe the grief and fear of the people by promises, now commands that this consolation shall be more widely spread; because it is his pleasure to diffuse his grace throughout the whole of Judea.

Lift up thy voice aloud, O Jerusalem. Formerly he had given to Jerusalem, and Zion the hope of this joyful message; now he commands that the same voice shall be spread and shall be heard through other cities, and, for this reason, gives orders that the loud voice shall be lifted up, and proclaimed from a lofty place. Although by the words “Zion” and “Jerusalem” he means the same thing, yet the repetition is emphatic; for he shews that one city excels all other cities, for no other reason than because God hath chosen it to be his sanctuary.

That bringest tidings. He gives to the city this appellation, because there the priests and Levites were instructed according to the injunctions of the Law, that they might be the teachers of the whole people, and by their labors might spread the doctrine of salvation. (Malachi 2:7.) Yet we ought carefully to observe this commendation which God bestows on his Church, that it may not be without a clear mark of distinction; for an assembly in which the preaching of heavenly doctrine is not heard does not deserve to be reckoned a Church. In this sense also, Paul calls it (1 Timothy 3:15) “the pillar and foundation of the truth;” for although God might have governed us by himself, and without the agency of men, yet he has assigned this office to his Church, and has committed to it the invaluable treasure of his Word. For the same reason it will be called in another passage, “the mother of all believers.” (Isaiah 54:1; Galatians 4:26.) Hence it follows that nothing is more absurd and wicked than for dumb idols to boast of the name of the Church, as is done in Popery.

We are likewise taught, that the Church has not been instructed by God, in order that she may keep her knowledge hidden within herself, but that she may publish what she has learned. Besides, he commands that grace shall be freely and boldly proclaimed, that prophets and teachers may not speak with timidity, as if it were a doubtful matter, but may shew that they are fully convinced of the certainty of those things which they promise, because they know well that “God, who cannot lie,” (Titus 1:2,) is the Author of them. He enjoins the witnesses of his grace to proceed from Zion, that they may fill with joy the whole of Judea.

Behold your God! This expression includes the sum of our happiness, which consists solely in the presence of God. It brings along with it an abundance of all blessings; and if we are destitute of it, we must be utterly miserable and wretched; and although blessings of every kind are richly enjoyed by us, yet if we are estranged from God, everything must tend to our destruction. From this circumstance it ought also to be remarked, that nothing is more opposite to faith than to estimate by the present appearances of things what God declares by his prophets, who at that time must have been struck dumb, had they not raised their views above the world, and thus, through the power of unshaken boldness and perseverance, dared to draw others along with them, that they might cherish good hopes when matters were at the worst. And indeed when wicked men and wickedness prevail, the greater the terror that is spread all around, and the greater the seeming wretchedness of the Church, the more ought we to extol the grace of God, and to point out his presence to believers. ¹¹³¹¹³     “A ceux qui la veulent contempler en foy.” “To those who wish to behold it by faith.”
