Isaiah 17:12
Woe to the multitude of many people, which 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!
Woe to the multitude of many people,..... Not as lamenting the people of the Jews with Hezekiah, as if they were the words of the prophet bemoaning their condition, saying, "O the multitude", &c. nor intending the Syrians and Israelites joined together against Judah; but the Assyrian army under Sennacherib, which consisted of people of many nations, and was very numerous, who are either threatened or called unto. A new subject is here begun, though a short one.
which make a noise like the noise of the seas; in a storm, when they foam and rage, and overflow the banks; this may refer both to the noise made by the march of such a vast army, the rattling of their armour and chariot wheels, and prancing of their horses; and to the hectoring, blustering, and blasphemous speeches of Sennacherib and Rabshakeh:
and to the rushing of nations, or "rushing nations",
that make a rushing like the rushing of mighty, waters; which denotes the fury and force with which they come, threatening to bear down all before them, as an inundation of water does.
