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 will I give him a command to take the spoil and to take the prey, and to tread them down like the mire of the streets. 7 However he doesn’t mean so, neither does his heart think so; but it is in his heart to destroy, and to cut off not a few nations. 8 For he says, “Aren’t all of my princes kings? 9 Isn’t Calno like Carchemish? Isn’t Hamath like Arpad? Isn’t Samaria like Damascus?” 10 As my hand has found the kingdoms of the idols, whose engraved images exceeded those of Jerusalem and of Samaria; 11 shall I not, as I have done to Samaria and her idols, so do to Jerusalem and her idols? 12 Therefore it will happen that, when the Lord has performed his whole work on Mount Zion and on Jerusalem, I will punish the fruit of the willful proud heart of the king of Assyria, and the insolence of his haughty looks.
Matthew Henry's Commentary on Isaiah 10:5-12
Commentary on Isaiah 10:5-19
(Read Isaiah 10:5-19)
See what a change sin made. The king of Assyria, in his pride, thought to act by his own will. The tyrants of the world are tools of Providence. God designs to correct his people for their hypocrisy, and bring them nearer to him; but is that Sennacherib's design? No; he designs to gratify his own covetousness and ambition. The Assyrian boasts what great things he has done to other nations, by his own policy and power. He knows not that it is God who makes him what he is, and puts the staff into his hand. He had done all this with ease; none moved the wing, or cried as birds do when their nests are rifled. Because he conquered Samaria, he thinks Jerusalem would fall of course. It was lamentable that Jerusalem should have set up graven images, and we cannot wonder that she was excelled in them by the heathen. But is it not equally foolish for Christians to emulate the people of the world in vanities, instead of keeping to things which are their special honour? For a tool to boast, or to strive against him that formed it, would not be more out of the way, than for Sennacherib to vaunt himself against Jehovah. When God brings his people into trouble, it is to bring sin to their remembrance, and humble them, and to awaken them to a sense of their duty; this must be the fruit, even the taking away of sin. When these points are gained by the affliction, it shall be removed in mercy. This attempt upon Zion and Jerusalem should come to nothing. God will be as a fire to consume the workers of iniquity, both soul and body. The desolation should be as when a standard-bearer fainteth, and those who follow are put to confusion. Who is able to stand before this great and holy Lord God?
