{o} Woe to the multitude of many people, who make a noise like the noise of the seas; and to the rushing of nations, that make a rushing like the rushing of mighty waters!

(o) The prophet laments, considering the horrible plague that was prepared against Israel by the Assyrians, who were infinite in number, and gathered from many nations.

Wesley's Notes

17:12 Woe - This is a new prophecy, added for the comfort of God's people. Many - Combined together against Judah. Seas - Who invade my land and people with great force, as the sea does when it enters into the land by a breach.

King James Translators' Notes

multitude: or, noise

mighty: or, many

Jamieson-Fausset-Brown Bible Commentary

Isa 17:12-18:7. Sudden Destruction of a Great Army in Judea (namely that of the Assyrian Sennacherib), AND Announcement of the Event to the Ethiopian Ambassadors.

The connection of this fragment with what precedes is: notwithstanding the calamities coming on Israel, the people of God shall not be utterly destroyed (Isa 6:12, 13); the Assyrian spoilers shall perish (Isa 17:13, 14).

12. Woe . multitude-rather, "Ho (Hark)! a noise of," &c. The prophet in vision perceives the vast and mixed Assyrian hosts (Hebrew, "many peoples," see on [713]Isa 5:26): on the hills of Judah (so "mountains," Isa 17:13): but at the "rebuke" of God, they shall "flee as chaff."

to the rushing . that make-rather, "the roaring . roareth" (compare Isa 8:7; Jer 6:23).

Matthew Henry's Concise Commentary

17:12-14 The rage and force of the Assyrians resembled the mighty waters of the sea; but when the God of Israel should rebuke them, they would flee like chaff, or like a rolling thing, before the whirlwind. In the evening Jerusalem would be in trouble, because of the powerful invader, but before morning his army would be nearly cut off. Happy are those who remember God as their salvation, and rely on his power and grace. The trouble of the believers, and the prosperity of their enemies, will be equally short; while the joy of the former, and the destruction of those that hate and spoil them, shall last for ever.

Matthew Henry's Whole Bible Commentary

Verses 12-14

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 (v. 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, Ps. 2:1; 93:3. 2. Triumphed over by the judgments of God. They thought to carry their point by dint of noise; but woe to them (v. 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 (Ps. 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, Ps. 83:13, 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 (v. 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, Ps. 26:5, 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.
