Isaiah 10:5-6, 12

¶Woe to Assyria, the rod of My anger [against Israel], The staff in whose hand is My indignation and fury [against Israel’s disobedience]! I send Assyria against a godless nation And commission it against the people of My wrath To take the spoil and to seize the plunder, And to trample them down like mud in the streets.

So when the Lord has completed all His work [of judgment] on Mount Zion and on Jerusalem, He will say, “I will punish the fruit [the thoughts, the declarations, and the actions] of the arrogant heart of the king of Assyria and the haughtiness of his pride.”
