Isaiah 10:6

I will send him against an hypocritical nation, one that is impure, corrupt, and wicked, and against the people of My wrath will I give him a charge, bidding Assyria smite Israel for its sins, to take the spoil, and to take the prey, and to tread them down like the mire of the streets, destroy their power, render them utterly helpless. So much the charge of the Lord to Assyria included, not, indeed, as if the Lord had sent this command by some messenger, but that He places even the heathen nations into His service to carry out His plans, to punish the disobedient.
