Charles Ellicott Commentary Isaiah 10:7

"Howbeit he meaneth not so, neither doth his heart think so; but it is in his heart to destroy, and to cut off nations not a few." — Isaiah 10:7 (ASV)

However, he does not mean so. —The thoughts which Isaiah puts into the mouth of the Assyrian are exactly in accord with the supreme egotism of the Sargon inscription, “I conquered,” “I besieged,” “I burnt,” “I killed,” “I destroyed”; this is the ever-recurring burden, mingled here and there with the boast that he is the champion of the great deities of Assyria, of Ishtar and of Nebo.
