Isaiah 10: 5 - 7, 13 - 16
5 Ah, Assyria, the rod of my anger, the staff of my fury!
6 Against a godless nation I send him, and against the people of my wrath I command him, to take spoil and seize plunder, and to tread them down like the mire of the streets.
7 But he does not so intend, and his mind does not so think; but it is in his mind to destroy, and to cut off nations not a few;
13 For he says: "By the strength of my hand I have done it, and by my wisdom, for I have understanding; I have removed the boundaries of peoples, and have plundered their treasures; like a bull I have brought down those who sat on thrones.
14 My hand has found like a nest the wealth of the peoples; and as men gather eggs that have been forsaken so I have gathered all the earth; and there was none that moved a wing, or opened the mouth, or chirped."
15 Shall the axe vaunt itself over him who hews with it, or the saw magnify itself against him who wields it? As if a rod should wield him who lifts it, or as if a staff should lift him who is not wood!
16 Therefore the Lord, the LORD of hosts, will send wasting sickness among his stout warriors, and under his glory a burning will be kindled, like the burning of fire.
