These verses read the doom of those that spoil and rob the people of God. If the Assyrians and Israelites invade and plunder Judah, if the Assyrian army take God's people captive and lay their country waste, let them know that ruin will be their lot and portion. They are here brought in, 1. Triumphing over the people of God. They relied upon their numbers. The Assyrian army was made up out of divers nations: it was the multitude of many people (Isa 17:12), by which weight they hoped to carry the cause. They were very noisy, like the roaring of the seas; they talked big, hectored, and threatened, to frighten God's people from resisting them, and all their allies from sending in to their aid. Sennacherib and Rabshakeh, in their speeches and letters, made a mighty noise to strike a terror upon Hezekiah and his people; the nations that followed them made a rushing like the rushing of many waters, and those mighty ones, that threaten to bear down all before them and carry away every thing that stands in their way. The floods have lifted up their voice, have lifted up their waves; such is the tumult of the people, and the heathen, when they rage, Psa 2:1; Psa 93:3. 2. Triumphed over by the judgments of God. They thought to carry their point by dint of noise; but woe to them (Isa 17:12), for he shall rebuke them, that is, God shall, one whom they little think of, have no regard to, stand in no awe of; he shall give them a check with an invisible hand, and then they shall flee afar off. Sennacherib, and Rabshakeh, and the remains of their forces, shall run away in a fright, and shall be chased by their own terrors, as the chaff of the mountains which stand bleak before the wind, and like a rolling thing before the whirlwind, like thistle-down (so the margin); they make themselves as chaff before the wind (Psa 35:5) and then the angel of the Lord (as it follows there), the same angel that slew many of them, shall chase the rest. God will make them like a wheel, or rolling thing, and then persecute them with his tempest and make them afraid with his storm, Psa 83:13, Psa 83:15. Note, God can dispirit the enemies of his church when they are most courageous and confident, and dissipate them when they seem most closely consolidated. This shall be done suddenly (Isa 17:14): At evening-tide they are very troublesome, and threaten trouble to the people of God; but before the morning they are not. At sleeping time they are cast into a deep sleep, Psa 26:5, Psa 26:6. It was in the night that the angel routed the Assyrian army. God can in a moment break the power of his church's enemies, even when it appears most formidable; and this is written for the encouragement of the people of God in all ages, when they find themselves an unequal match for their enemies; for this is the portion of those that spoil us, they shall themselves be spoiled. God will plead his church's cause, and those that meddle do it to their own hurt.

The nations shall rush like the rushing of many waters,.... With great force and noise, and run over the whole land, as the Assyrian army did, until it came to Jerusalem, and there it stopped; see Isa 8:7,

but God shall rebuke them; as he did the waters of the Red Sea, Psa 106:9 and as Christ rebuked the winds and sea, and made a calm, Mat 8:26. The word "God" is not in the text, but rightly supplied; for as none but he can rebuke the mighty waters of the sea, so none but he could have destroyed such an army in the manner it was, and wrought such a salvation for his people. The phrase, is expressive both of his wrath and power.

And they shall flee afar off; from Jerusalem to Nineveh, reckoned to be six hundred and eighty four miles from thence: or, "he shall flee afar off" (x); that is, Sennacherib, and the few that escaped with him, for, his army was destroyed; see Kg2 19:36,

and shall be chased as the chaff of the mountains before the wind; chaff upon the floor is easily chased away with the fan, and much more easily chaff upon the mountains with the wind; it was usual with the Jews to thresh their corn, and winnow it on hills and mountains, to which the allusion is; see Ch2 3:1 or "the dust of the mountains", as some (y) render it, which is more exposed to the wind than that in the valleys. Kings and great men of the earth are but as dust with God; and the higher they are, or they exalt themselves, the more they are exposed to the power of his wrath, and as easily cast down as the dust is scattered by the wind:

and like a rolling thing before the whirlwind; or "like a wheel" (z), as the word is sometimes rendered; or any round thing, as a round wisp of straw or stubble, which is easily and swiftly moved and rolled along, especially by a strong wind. Jarchi interprets it of the flower of thorns; that is, the down of the thistle, which, when blown off, rolls up, and, being exceeding light, is carried away at once; see Psa 83:13 all which shows what poor light things the greatest of men are in the hands of God, and with what ease he can chase them from place to place, and out of the world, when it is his pleasure.

shall . . . shall--rather, "God rebuketh (Psa 9:5) them, and they flee--are chased"; the event is set before the eyes as actually present, not future.

chaff of . . . mountains--Threshing floors in the East are in the open air on elevated places, so as to catch the wind which separates the chaff from the wheat (Psa 88:13; Hos 13:3).

rolling thing--anything that rolls: stubble.
