Isaiah 10:5 in the King James Version
O Assyrian, the rod of mine anger, and the staff in their hand is mine indignation.
Context
4 They will only bow down under the prisoners, and will fall under the slain. For all this his anger is not turned away, but his hand is stretched out still.
5 Alas Assyrian, the rod of my anger, the staff in whose hand is my indignation!
6 I will send him against a profane nation, and against the people who anger me I will give him a command to take the plunder and to take the prey, and to tread them down like the mire of the streets.
