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

the enemy armies appear to be a powerful force that no one can stop. AT: "The armies from the nations will roar and come rushing in like the mighty waters." (See: rc://en/ta/man/translate/figs-parallelism and rc://en/ta/man/translate/figs-simile)

as the dead weeds on the mountains before the wind, and like weeds whirling before a storm

the armies seemed powerful but God will easily stop them.

loot us...rob us

The word "us" refers to Isaiah and includes the people of Judah. (See: rc://en/ta/man/translate/figs-inclusive)
