And the mountains shall be molten under Him - It has been thought that this is imagery, taken from volcanic eruptions ; but, although there is a very remarkable volcanic district just outside of Gilead, it is not thought to have been active at times so late as these; nor were the people to whom the words were said, familiar with it. Fire, the real agent at the end of the world, is, meanwhile, the symbol of God's anger, as being the most terrible of His instruments of destruction: whence God revealed Himself as a consuming fire Deuteronomy 4:24, and at this same time said by Isaiah; "For behold, the Lord will come with fire ... to render His anger with fury, and His rebuke with flames of fire" Isaiah 66:15.

And the valleys shall be cleft as wax before the fire - It seems natural that the mountains should be cleft; but the valleys , so low already! This speaks of a yet deeper dissolution; of lower depths beyond our sight or knowledge, into the very heart of the earth. Sanch.: "This should they fear, who will to be so low; who, so far from lifting themselves to heavenly things, pour out their affections on things of earth, meditate on and love earthly things, and forgetful of the heavenly, choose to fix their eyes on earth. These the wide gaping of the earth which they loved, shall swallow: to them the cleft valleys shall open an everlasting sepulchre, and, having received them, shall never part with them."

Highest and lowest, first and last, shall perish before Him. The pride of the highest, kings and princes, priests and judges, shall sink and melt away beneath the weight and Majesty of His glory; the hardness of the lowest, which would not open itself to Him, shall be cleft in twain before Him.

As wax before the fire - (See Psalm 97:5), melting away before Him by whom they were not softened, vanishing into nothingness. Metals melt, changing their form only; wax, so as to cease to be.

As the waters poured down - (As a stream or cataract, so the word means .)

A steep place - Down to the very edge, it is borne along, one strong, smooth, unbroken current; then, at once, it seems to gather its strength, for one great effort. But to what end? To fall, with the greater force, headlong, scattered in spray, foam and froth; dissipated, at times, into vapor, or reeling in giddy eddies, never to return. In Judea, where the autumn rains set in with great vehemence, the waters must have been often seen pouring in their little tumultuous brooklets down the mountain side , hastening to disappear, and disappearing the faster, the more vehemently they rolled along . Both images exhibit the inward emptiness of sinners, man's utter helplessness before God. They need no outward impulse to their destruction. Jerome: "Wax endureth not the nearness of the fire, and the waters are carried headlong. So all of the ungodly, when the Lord cometh, shall be dissolved and disappear." At the end of the world, they shall be gathered into bundles, and cast away.

And the mountains shall be molten under him,.... As Sinai was when he descended on it, and as all nations will be at the general conflagration; but here the words are to be taken, not literally, but figuratively, for the kingdoms of Israel and Judah, and for the kings, and princes, and great men in them, that lifted up their heads as high, and thought themselves as secure, as mountains; yet when the judgments of God should fall upon them, their hearts would melt through fear under him; as well as all their glory and greatness depart from them, and they be no more what they were before, but levelled with the meanest subject:

and the valleys shall be cleft: have chasms made in them by the melting of the mountains, or by the flow of water from the hills: these may design the lower sort of people, who shall have their share in this calamity; the inhabitants of the valleys and country villages; who, though mean and low, shall be lower still, and lose that little substance, that liberty and those privileges, they had; as valleys may be cleft, and open, and sink into the lower parts of the earth; so it is signified that these people should be in a more depressed state and condition:

as wax before the fire; melts, and cannot stand the force of it; so the mountains should melt at the presence of the Lord; and kingdoms and states, and the greatest and mightiest of men in them, would not be able to stand before the fierceness of his wrath; see Psalm 68:2;

and as the waters that are poured down a steep place; that run with great swiftness, force, and rapidity, and there is no stopping them; so should the judgments of God come down upon the lower sort of people, the inhabitants of the valleys; neither high nor low would escape the indignation of the Lord, or be able to stand against it, or stand up under it.

And the mountains shall be molten under him, and the valleys shall be cleft, as wax before the fire, and as the waters that are poured down a steep place.

1:4 Cleft - Or rent in sunder, broken up and slide away.

a steep...: Heb. a descent

4. Imagery from earthquakes and volcanic agency, to describe the terrors which attend Jehovah's coming in judgment (compare Jud 5:5). Neither men of high degree, as the mountains, nor men of low degree, as the valleys, can secure themselves or their land from the judgments of God.

as wax-(Ps 97:5; compare Isa 64:1-3). The third clause, "as wax," &c., answers to the first in the parallelism, "the mountains shall be molten"; the fourth, "as the waters," &c., to the second, "the valleys shall be cleft." As wax melts by fire, so the mountains before God, at His approach; and as waters poured down a steep cannot stand but are diffused abroad, so the valleys shall be cleft before Jehovah.

1:1-7 The earth is called upon, with all that are therein, to hear the prophet. God's holy temple will not protect false professors. Neither men of high degree, as the mountains, nor men of low degree, as the valleys, can secure themselves or the land from the judgments of God. If sin be found in God's people he will not spare them; and their sins are most provoking to him, for they are most reproaching. When we feel the smart of sin, it behoves us to seek what is the sin we smart for. Persons and places most exalted, are most exposed to spiritual diseases. The vices of leaders and rulers shall be surely and sorely punished. The punishment answers the sin. What they gave to idols, never shall prosper, nor do them any good. What is got by one lust, is wasted on another.
