For he has said, ‘With the power of my hand I shall certainly act, and with my wisdom, for I do have understanding; and I shall remove the boundaries of peoples, and their things stored up I shall certainly pillage, and I shall bring down the inhabitants just like a powerful one.

The Assyrian imperialist would think that he had the power, the wisdom and the understanding to make his conquests earth wide.

So “the Assyrian” would do what he pleased with the conquered territories, changing or wiping out the boundary lines or deporting people from their native land, just as when “the Assyrian” deported the surviving Israelites from the God-given land of Israel to Assyria and repeopled the emptied land with other national groups.
