Albert Barnes Commentary Isaiah 33:13

"Hear, ye that are far off, what I have done; and, ye that are near, acknowledge my might." — Isaiah 33:13 (ASV)

Hear, you that are far off — This is an address of Yahweh, indicating that the destruction of the Assyrian army would be so significant that it would be known to distant nations and would serve as a warning to them.

You that are near — You Jews; or the nations immediately adjacent to Judea. The phrase far and near, is equivalent to all.
