The closing words of the foregoing paragraph (You shall be left as a beacon upon a mountain) some understand as a promise that a remnant of them should be reserved as monuments of mercy; and here the prophet tells them what good times should succeed these calamities. Or the first words in this paragraph may be read by way of antithesis, Notwithstanding this, yet will the Lord wait that he may be gracious. The prophet, having shown that those who made Egypt their confidence would be ashamed of it, here shows that those who sat still and made God alone their confidence would have the comfort of it. It is matter of comfort to the people of God, when the times are very bad, that all will be well yet, well with those that fear God, when we say to the wicked, It shall be ill with you.

I. God will be gracious to them and will have mercy on them. This is the foundation of all good. If we find favour with God, and he have mercy upon us, we shall have comfort according to the time that we have been afflicted.

1. The mercy in store for them is very affectingly expressed. (1.) “He will wait to be gracious (Isa. 30:18); he will wait till you return to him and seek his face, and then he will be ready to meet you with mercy. He will wait, that he may do it in the best and fittest time, when it will be most for his glory, when it will come to you with the most pleasing surprise. He will continually follow you with his favours, and not let slip any opportunity of being gracious to you.” (2.) “He will stir up himself to deliver you, will be exalted, will be raised up out of his holy habitation (Zech. 2:13), that he may appear for you in more than ordinary instances of power and goodness; and thus he will be exalted, that is, he will glorify his own name. This is what he aims at in having mercy on his people.” (3.) He will be very gracious (Isa. 30:19), and this in answer to prayer, which makes his kindness doubly kind: “He will be gracious to thee, at the voice of thy cry, the cry of thy necessity, when that is most urgent—the cry of thy prayer, when that is most fervent. When he shall hear it, there needs no more; at the first word he will answer thee, and say, Here I am.” Herein he is very gracious indeed. In particular, [1.] Those who were disturbed in the possession of their estates shall again enjoy them quietly. When the danger is over the people shall dwell in Zion, at Jerusalem, as they used to do; they shall dwell safely, free from the fear of evil. [2.] Those who were all in tears shall have cause to rejoice, and shall weep no more; and those who dwell in Zion, the holy city, will find enough there to wipe away tears from their eyes.

2. This is grounded upon two great truths: (1.) That the Lord is a God of judgment; he is both wise and just in all the disposals of his providence, true to his word and tender of his people. If he correct his children, it is with judgment (Jer. 10:24), with moderation and discretion, considering their frame. We think we may safely refer ourselves to a man of judgment; and shall we not commit our way to a God of judgment? (2.) That therefore all those are blessed who wait for him, who not only wait on him with their prayers, but wait for him with their hopes, who will not take any indirect course to extricate themselves out of their straits, or anticipate their deliverance, but patiently expect God’s appearances for them in his own way and time. Because God is infinitely wise, those are truly happy who refer their cause to him.

II. They shall not again know the want of the means of grace, Isa. 30:20, 21. Here, 1. It is supposed that they might be brought into straits and troubles after this deliverance was wrought for them. It was promised (Isa. 30:19), that they should weep no more and that God would be gracious to them; and yet here it is taken for granted that God may give them the bread of adversity and the water of affliction, prisoners’ fare (1 Kgs. 22:27), coarse and sorry food, such as the poor use. When one trouble is over we know not how soon another may succeed; and we may have an interest in the favour of God, and such consolations as are sufficient to prohibit weeping, and yet may have bread of adversity given us to eat and water of affliction to drink. Let us therefore not judge of love or hatred by what is before us. 2. It is promised that their eyes should see their teachers, that is, that they should have faithful teachers among them, and should have hearts to regard them and not slight them as they had done; and then they might the better be reconciled to the bread of adversity and the water of affliction. It was a common saying among the old Puritans, Brown bread and the gospel are good fare. A famine of bread is not so great a judgment as a famine of the word of God, Amos 8:11, 12. It seems that their teachers had been removed into corners (probably being forced to shift for their safety in the reign of Ahaz), but it shall be so no more. Veritas non quaerit angulos—Truth seeks no corners for concealment. But the teachers of truth may sometimes be driven into corners for shelter; and it goes ill with the church when it is so, when the woman with her crown of twelve stars is forced to flee into the wilderness (Rev. 12:6), when the prophets are hidden by fifty in a cave, 1 Kgs. 18:4. But God will find a time to call the teachers out of their corners again, and to replace them in their solemn assemblies, which shall see their own teachers, the eyes of all the synagogue being fastened on them, Luke 4:20. And it will be the more pleasing because of the restraint they have been for some time under, as light out of darkness, as life from the dead. To all that love God and their own souls this return of faithful teachers out of their corners, especially with a promise that they shall not be removed into corners any more, is the most acceptable part of any deliverance, and has comfort enough in it to sweeten even the bread of adversity and the water of affliction. But this is not all: 3. It is promised that they shall have the benefit, not only of the public ministry, but of private and particular admonition and advice (Isa. 30:21): “Thy ears shall hear a word behind thee, calling after thee as a man calls after a traveller that he sees going out of his road.” Observe, (1.) Whence this word shall come—from behind thee, from some one whom thou dost not see, but who sees thee. “Thy eyes see thy teachers; but this is a teacher out of sight, it is thy own conscience, which shall now by the grace of God be awakened to do its office.” (2.) What the word shall be: “This is the way, walk you in it. When thou art doubting, conscience shall direct thee to the way of duty; when thou art dull and trifling, conscience shall quicken thee in that way.” As God has not left himself without witness, so he has not left us without guides to show us our way. (3.) The seasonableness of this word: It shall come when you turn to the right hand or to the left. We are very apt to miss our way; there are turnings on both hands, and those so tracked and seemingly straight that they may easily be mistaken for the right way. There are right-hand and left-hand errors, extremes on each side virtue; the tempter is busy courting us into the by-paths. It is happy then if by the particular counsels of a faithful minister or friend, or the checks of conscience and the strivings of God’s Spirit, we be set right and prevented from going wrong. (4.) The success of this word: “It shall not only be spoken, but thy ears shall hear it; whereas God has formerly spoken once, yea, twice, and thou hast not perceived it (Job 33:14), now thou shalt listen attentively to these secret whispers, and hear them with an obedient ear.” If God gives us not only the word, but the hearing ear, not only the means of grace, but a heart to make a good use of those means, we have reason to say, He is very gracious to us, and reason to hope he has yet further mercy in store for us.

III. They shall be cured of their idolatry, shall fall out with their idols, and never be reconciled to them again, Isa. 30:22. The deliverance God shall work for them shall convince them that it is their interest, as well as duty, to serve him only; and they shall own that, as their trouble was brought upon them for their idolatries, so it was removed upon condition that they should not return to them. This is also the good effect of their seeing their teachers and hearing the word behind them; by this it shall appear that they are the better for the means of grace they enjoy—they shall break off from their best-beloved sin. Observe, 1. How foolishly mad they had formerly been upon their idols, in the day of their apostasy. Idolaters are said to be mad upon their idols (Jer. 50:38), doatingly fond of them. They had graven images of silver, and molten images of gold, and, though gold needs no painting, they had coverings and ornaments on these; they spared no cost in doing honour to their idols. 2. How wisely mad (if I may so speak) they now were at their idols, what a holy indignation they conceived against them in the day of their repentance. They not only degraded their images, but defaced them, not only defaced them, but defiled them; they not only spoiled the shape of them, but in a pious fury threw away the gold and silver they were made of, though otherwise valuable and convertible to a good use. They could not find in their hearts to make any vessel of honour of them. The rich clothes wherewith their images were dressed up they cast away as a filthy cloth which rendered those that touched it unclean until the evening, Lev. 15:23. Note, To all true penitents sin has become very odious; they loathe it, and loathe themselves because of it; they cast it away to the dunghill, the fittest place for it, nay, to the cross, for they crucify the flesh; their cry against it is, Crucify it, crucify it. They say unto it, Abi hinc in malam rem—Get thee hence. They are resolved never to harbour it any more. They put as far from as they can all the occasions of sin and temptations to it, though they are as a right eye or a right hand, and protest against it as Ephraim did (Hos. 14:8), What have I to do any more with idols? Probably this was fulfilled in many particular persons, who, by the deliverance of Jerusalem from Sennacherib’s army, were convinced of the folly of their idolatry and forsook it. It was fulfilled in the body of the Jewish nation at their return from their captivity in Babylon, for they abhorred idols ever after; and it is accomplished daily in the conversion of souls, by the power of divine grace, from spiritual idolatry to the fear and love of God. Those that join themselves to the Lord must abandon every sin, and say unto it, Get thee hence.

IV. God will then give them plenty of all good things. When he gives them their teachers, and they give him their hearts, so that they begin to seek the kingdom of God and the righteousness thereof, then all other things shall be added to them Matt. 6:33. And when the people are brought to praise God then shall the earth yield her increase, and with it God, even our own God, shall bless us, Ps. 67:5, 6. So it follows here: “When you shall have abandoned your idols, then shall God give the rain of your seed,” Isa. 30:23. When we return to God in a way of duty he will meet us with his favours. 1. God will give you rain of your seed, rain to water the seed you sow, just at the time that it calls for it, as much as it needs and no more. Observe, How man’s industry and God’s blessing concur to the good things we enjoy relating to the life that now is: Thou shalt sow the ground, that is thy part, and then God will give the rain of thy seed, that is his part. It is so in spiritual fruit; we must take pains with our hearts and then wait on God for his grace. 2. The increase of the earth shall be rich and good, and every thing the best of the kind; it shall be fat and fat, very fat and very good, fat and plenteous (so we read it), good and enough of it. Your land shall be Canaan indeed; it was remarkably so after the defeat of Sennacherib, by the special blessing of God, Isa. 37:30. God would thus repair the losses they sustained by that devastation. 3. Not only the tillage, but the pasture-ground should be remarkably fruitful: The cattle shall feed in large pastures; those that are at grass shall have room enough, and the oxen and asses that are kept up for use, to ear the ground, which must be the better fed for their being worked, shall eat clean provender. The corn shall not be given them in the chaff as usual, to make it go the further, but they shall have good clean corn fit for man’s use, being winnowed with the fan. The brute-creatures shall share in the abundance; it is fit they should, for they groan under the burden of the curse which man’s sin has brought upon the earth. 4. Even the tops of the mountains, that used to be barren, shall be so well watered with the rain of heaven that there shall be rivers and streams there, and running down thence to the valleys (Isa. 30:25), and this in the day of the great slaughter that should be made by the angel in the camp of the Assyrians, when the towers and batteries they had erected for the carrying on of the siege of Jerusalem, the army being slain, should fall of course. It is probable that this was fulfilled in the letter of it, and that about the same time that that army was cut off there were extraordinary rains in mercy to the land.

V. The effect of all this should be extraordinary comfort and joy to the people of God, Isa. 30:26. Light shall increase; that is, knowledge shall increase (when the prophecies are accomplished they shall be fully understood) or rather triumph shall: the light of the joy that is sown for the righteous shall now come up with a great increase. The light of the moon shall become as bright and as strong as that of the sun, and that of the sun shall increase proportionably and be as the light of seven days; every one shall be much more cheerful and appear much more pleasant than usual. There shall be a high spring-tide of joy in Judah and Jerusalem, upon occasion of the ruin of the Assyrian army, when the Lord binds up the breach of his people, not only saves them from being further wounded, but heals the wounds that have been given them by this invasion and makes up all their losses. The great distress they were reduced to, their despair of relief, and the suddenness of their deliverance, would much augment their joy. This is not unfitly applied by many to the light which the gospel brought into the world to those that sat in darkness, which has far exceeded the Old-Testament light as that of the sun does that of the moon, and which proclaims healing to the broken-hearted, and the binding up of their wounds.
