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?
Isa 10:5-34 and Isa 11:12. Destruction of the Assyrians; Coming of Messiah; Hymn of Praise.
Isa 10:9, 11 show that Samaria was destroyed before this prophecy. It was written when Assyria proposed (a design which it soon after tried to carry out under Sennacherib) to destroy Judah and Jerusalem, as it had destroyed Samaria. This is the first part of Isaiah's prophecies under Hezekiah. Probably between 722 and 715 B.C. (see Isa 10:27).
5. O Assyrian, &c.—rather, "What, ho (but Maurer, Woe to the) Assyrian! He is the rod and staff of Mine anger (My instrument in punishing, Jer 51:20; Ps 17:13). In their hands is Mine indignation" [Horsley, after Jerome]. I have put into the Assyrians' hands the execution of Mine indignation against My people.
