Commentaries
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.
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).
