III. A terrible prediction of destroying judgments which should come upon Judah and Israel, which had its accomplishment soon after in Israel, and at length in Judah; for it is foretold, 1. That God himself will appear against them, v. 3. They boasted of themselves and their relation to God, as if that would secure them; but, though God never deceives the faith of the upright, he will disappoint the presumption of the hypocrites, for, behold, the Lord comes forth out of his place, quits his mercy-seat, where they thought they had him fast, and prepares his throne for judgment; his glory departs, for they drive it from them. God's way towards this people had long been a way of mercy, but now he changes his way, he comes out of his place, and will come down. He had seemed to retire, as one regardless of what was done, but now he will show himself, he will rend the heavens, and will come down, not as sometimes, in surprising mercies, but in surprising judgments, to do things not for them, but against them, which they looked not for, Isa. lxiv. 1; xxvi. 21. 2. That when the Creator appears against them it shall be in vain for any creature to appear for them. He will tread with contempt and disdain upon the high places of the earth, upon all the powers that are advanced in competition with him or in opposition to him; and he will so tread upon them as to tread them down and level them. High places, set up for the worship of idols or for military fortifications, shall all be trodden down and trampled into the dust. Do men trust to the height and strength of the mountains and rocks, as if they were sufficient to bear up their hopes and bear off their fears? They shall be molten under him, melted down as wax before the fire, Ps. lxviii. 2. Do they trust to the fruitfulness of the valleys, and their products? They shall be cleft, or rent, with those fiery streams that shall come pouring down from the mountains when they are melted. They shall be ploughed and washed away as the ground is by the waters that are poured down a steep place. God is said to cleave the earth with rivers, Hab. iii. 9. Neither men of high degree, as the mountains, nor men of low degree, as the valleys, shall be able to secure either themselves or the land from judgments of God, when they are sent with commission to lay all waste, and, like a sweeping rain, to leave no food, Prov. xxviii. 3. This is applied particularly to the head city of Israel, which they hoped would be a protection to the kingdom (v. 6): I will make Samaria, that is now a rich and populous city, as a heap of the field, as a heap of dung laid there to be spread, or as a heap of stones gathered together to be carried away, and as plantings of a vineyard, as hillocks of earth raised to plant vines in. God will make of that city a heap, of that defenced city a ruin, Isa. xxv. 2. Their altars had been as heaps in the furrows of the fields (Hos. xii. 11) and now their houses shall be so, as ruinous heaps. The stones of the city are poured down into the valley by the fury of the conqueror, who will thus be revenged on those walls that so long held out against him. They shall be quite pulled down, so that the very foundations shall be discovered, that had been covered by the superstructure; and not one stone shall be left upon another.
