Charles Ellicott Commentary Isaiah 17:12

"Ah, the uproar of many peoples, that roar like the roaring of the seas; and the rushing of nations, that rush like the rushing of mighty waters!" — Isaiah 17:12 (ASV)

Woe to the multitude of many people. —The three Isaiah 17:12-14 stand as an isolated fragment, probably placed here as beginning like Isaiah 18:1. They may have been connected with the progress of Sennacherib’s army. In the rushing of mighty waters to describe the march of an army, we have a parallel to Isaiah 8:7-8.
