O destroying mountain - A volcano which by its flames and hot lava-streams "destroys the whole land."

A burnt mountain - A burned-out mountain, of which the crater alone remains. Such was Babylon. Its destructive energy under Nebuchadnezzar was like the first outbreak of volcanic fires; its rapid collapse under his successors was as the same volcano when its flames have burned out, and its crater is falling in upon itself.

O destroying mountain - An epithet which he applies to the Babylonish government; it is like a burning mountain, which, by vomiting continual streams of burning lava inundates and destroys all towns, villages fields, etc., in its vicinity.

And roll thee down from the rocks - I will tumble thee from the rocky base on which thou restest. The combustible matter in thy bowels being exhausted, thou shalt appear as an extinguished crater; and the stony mutter which thou castest out shall not be of sufficient substance to make a foundation stone for solidity, or a corner stone for beauty, Jeremiah 51:26. Under this beautiful and most expressive metaphor, the prophet shows the nature of the Babylonish government; setting the nations on fire, deluging and destroying them by its troops, till at last, exhausted, it tumbles down, is extinguished, and leaves nothing as a basis to erect a new form of government on; but is altogether useless, like the cooled lava, which is, properly speaking, fit for no human purpose.

Behold, I am against thee, O destroying mountain, saith the Lord, which destroyest all the earth,.... Babylon is called a mountain, though situated in a plain, because of its high walls, lofty towers, and hanging gardens, which made it look at a distance like a high mountain, as Lebanon, and others: or because it was a strong fortified city; so the Targum renders it, O destroying city: or because of its power and grandeur as a monarchy, it being usual to compare monarchies to mountains; see Isaiah 2:2; here called a "destroying" one for a reason given, because it destroyed all the earth, all the nations and kingdoms of it: the same character is given of mystical Babylon and its inhabitants, Revelation 11:18,

and I will stretch out mine hand upon thee: in a way of vindictive wrath, pouring it out upon her, and inflicting his judgments on her; laying hold on and seizing her in a furious manner, as a man does his enemy, when he has found him:

and roll them down from the rocks; towers and fortresses in Babylon, which looked like rocks, but should be now demolished:

and will make thee a burnt mountain: reduced to cinders and ashes by the conflagration of it: or, "a burning mountain": like Etna and Vesuvius; we never read of the burning of literal Babylon, but we do of mystical Babylon: see Revelation 18:8; and with this compare Revelation 8:8. The Targum renders it, a burnt city.

Behold, I am against thee, O destroying {o} mountain, saith the LORD, which destroyest all the earth: and I will stretch out my hand upon thee, and roll thee down from the {p} rocks, and will make thee a burnt mountain.

(o) Not that Babylon stood on a mountain but because it was strong and seemed invincible.

(p) From your strongholds and fortresses.

51:25 Mountain - Babylon was very high for its power, and greatness, and had very high walls and towers, that it looked at a distance like an high rocky mountain. They had destroyed many people. Burnt - Thy cities and towers which appear like a mountain shall be burnt.

Margin O destroying mountain

See note 2 on Babylon, Isa 13:1 Zech 4:7, See Scofield Note: "Isa 13:1".

25. destroying mountain-called so, not from its position, for it lay low (Jer 51:13; Ge 11:2, 9), but from its eminence above other nations, many of which it had "destroyed"; also, because of its lofty palaces, towers, hanging gardens resting on arches, and walls, fifty royal cubits broad and two hundred high.

roll thee down from the rocks-that is, from thy rock-like fortifications and walls.

burnt mountain-(Re 8:8). A volcano, which, after having spent itself in pouring its "destroying" lava on all the country around, falls into the vacuum and becomes extinct, the surrounding "rocks" alone marking where the crater had been. Such was the appearance of Babylon after its destruction, and as the pumice stones of the volcano are left in their place, being unfit for building, so Babylon should never rise from its ruins.

51:1-58 The particulars of this prophecy are dispersed and interwoven, and the same things left and returned to again. Babylon is abundant in treasures, yet neither her waters nor her wealth shall secure her. Destruction comes when they did not think of it. Wherever we are, in the greatest depths, at the greatest distances, we are to remember the Lord our God; and in the times of the greatest fears and hopes, it is most needful to remember the Lord. The feeling excited by Babylon's fall is the same with the New Testament Babylon, Re 18:9,19. The ruin of all who support idolatry, infidelity, and superstition, is needful for the revival of true godliness; and the threatening prophecies of Scripture yield comfort in this view. The great seat of antichristian tyranny, idolatry, and superstition, the persecutor of true Christians, is as certainly doomed to destruction as ancient Babylon. Then will vast multitudes mourn for sin, and seek the Lord. Then will the lost sheep of the house of Israel be brought back to the fold of the good Shepherd, and stray no more. And the exact fulfilment of these ancient prophecies encourages us to faith in all the promises and prophecies of the sacred Scriptures.
