Isaiah 10:5-7

5 O Assyrian, the rod of my anger, and the staff in their hand is my indignation.

6 I will send him against an hypocritical nation, and against the people of my wrath will I give him a charge, to take the spoil, and to take the prey, and to tread them down like the mire of the streets.

7 However, he means not so, neither does his heart think so; but it is in his heart to destroy and cut off nations not a few.
