18 Therefore Yahweh will wait, that he may be gracious to you; and therefore he will be exalted, that he may have mercy on you, for Yahweh is a God of justice. Blessed are all those who wait for him. 19 For the people will dwell in Zion at Jerusalem. You will weep no more. He will surely be gracious to you at the voice of your cry. When he hears you, he will answer you. 20 Though the Lord may give you the bread of adversity and the water of affliction, yet your teachers won’t be hidden anymore, but your eyes will see your teachers; 21 and when you turn to the right hand, and when you turn to the left, your ears will hear a voice behind you, saying, “This is the way. Walk in it.” 22 You shall defile the overlaying of your engraved images of silver, and the plating of your molten images of gold. You shall cast them away as an unclean thing. You shall tell it, “Go away!” 23 He will give the rain for your seed, with which you will sow the ground; and bread of the increase of the ground will be rich and plentiful. In that day, your livestock will feed in large pastures. 24 The oxen likewise and the young donkeys that till the ground will eat savory provender, which has been winnowed with the shovel and with the fork. 25 There shall be brooks and streams of water on every lofty mountain and on every high hill in the day of the great slaughter, when the towers fall. 26 Moreover the light of the moon will be like the light of the sun, and the light of the sun will be seven times brighter, like the light of seven days, in the day that Yahweh binds up the fracture of his people, and heals the wound they were struck with.
27 Behold, the name of Yahweh comes from far away, burning with his anger, and in thick rising smoke. His lips are full of indignation, and his tongue is as a devouring fire. 28 His breath is as an overflowing stream that reaches even to the neck, to sift the nations with the sieve of destruction; and a bridle that leads to ruin will be in the jaws of the peoples. 29 You will have a song, as in the night when a holy feast is kept; and gladness of heart, as when one goes with a flute to come to Yahweh’s mountain, to Israel’s Rock. 30 Yahweh will cause his glorious voice to be heard, and will show the descent of his arm, with the indignation of his anger, and the flame of a devouring fire, with a blast, storm, and hailstones. 31 For through the voice of Yahweh the Assyrian will be dismayed. He will strike him with his rod. 32 Every stroke of the rod of punishment, which Yahweh will lay on him, will be with the sound of tambourines and harps. He will fight with them in battles, brandishing weapons. 33 For his burning place has long been ready. Yes, for the king it is made ready. He has made its pyre deep and large with fire and much wood. Yahweh’s breath, like a stream of sulfur, kindles it.
Matthew Henry's Commentary on Isaiah 30:18-33
Commentary on Isaiah 30:8-18
(Read Isaiah 30:8-18)
The Jews were the only professing people God then had in the world, yet many among them were rebellious. They had the light, but they loved darkness rather. The prophets checked them in their sinful pursuits, so that they could not proceed without fear; this they took amiss. But faithful ministers will not be driven from seeking to awaken sinners. God is the Holy One of Israel, and so they shall find him. They did not like to hear of his holy commandments and his hatred of sin; they desired that they might no more be reminded of these things. But as they despised the word of God, their sins undermined their safety. Their state would be dashed in pieces like a potter's vessel. Let us return from our evil ways, and settle in the way of duty; that is the way to be saved. Would we be strengthened, it must be in quietness and in confidence, keeping peace in our own minds, and relying upon God. They think themselves wiser than God; but the project by which they thought to save themselves was their ruin. Only here and there one shall escape, as a warning to others. If men will not repent, turn to God, and seek happiness in his favour and service, their desires will but hasten their ruin. Those who make God alone their confidence, will have comfort. God ever waits to be gracious to all that come to him by faith in Christ, and happy are those who wait for him.
Commentary on Isaiah 30:19-26
(Read Isaiah 30:19-26)
God's people will soon arrive at the Zion above, and then they will weep no more for ever. Even now they would have more comfort, as well as holiness, if they were more constant in prayer. A famine of bread is not so great a judgment as a famine of the word of God. There are right-hand and left-hand errors; the tempter is busy courting us into by-paths. It is happy if, by the counsels of a faithful minister or friend, or the checks of conscience, and the strivings of God the Spirit, we are set right when doubting, and prevented from going wrong. They shall be cured of their idolatry. To all true penitents sin becomes very hateful. This is shown daily in the conversion of souls, by the power of Divine grace, to the fear and love of God. Abundant means of grace, with the influences of the Holy Spirit, would be extended to places destitute of them. The effect of this should be comfort and joy to the people of God. Light, that is, knowledge, shall increase. This is the light which the gospel brought into the world, and which proclaims healing to the broken-hearted.
Commentary on Isaiah 30:27-33
(Read Isaiah 30:27-33)
God curbs and restrains from doing mischief. With a word he guides his people into the right way, but with a bridle he turns his enemies upon their own ruin. Here, in threatening the ruin of Sennacherib's army, the prophet points at the final and everlasting destruction of all impenitent sinners. Tophet was a valley near Jerusalem, where fires were continually burning to destroy things that were hurtful and offensive, and there the idolatrous Jews caused their children to pass through the fire to Moloch. This denotes the certainty of the destruction, as an awful emblem of the place of torment in the other world. No oppressor shall escape the Divine wrath. Let sinners then flee to Christ, seeking to be reconciled to Him, that they may be safe and happy, when destruction from the Almighty shall sweep away all the workers of iniquity.
