Isaiah 10:5

O Assyrian: so it is God's call or invitation to him to take the charge, and set upon the work. Or, Woe to the Assyrian ! because though he do my work, yet he doth it in a wicked manner, and for wicked ends, as we shall see. The rod of mine anger; the instrument of mine anger. wherewith I shall chastise my people. The staff in their hand is mine indignation; mine anger against my people puts the weapons of war into their hand, and gives them strength and success in this expedition.
