Therefore shall the Lord, the Lord of hosts
Because of the pride, and arrogance, and vain boasting of the Assyrian monarch, which was resented by the Lord, he is threatened with what follows; and in order to humble him, and to show that God is above him, these titles are used; "the Lord", the Lord of the whole earth, and the King of kings, and Lord of lords; "the Lord of hosts", of armies above and below, of more and greater armies than what the king of Assyria was lord of; and therefore he might be assured that what is hereafter threatened would be fulfilled, namely, send among his fat ones leanness;
the Targum is, among his princes, who abounded in riches and honour; or his army, and the chiefs in it, the mighty and strong; and by "leanness" is meant destruction and death, which came upon his army, and the great men of it, immediately from the hand of God; see ( Psalms 106:15 ) compared with ( Numbers 11:33 ) : and under his glory he shall kindle a burning, like the burning of
a fire;
that is, under his army, which was great and glorious, very numerous, and well accoutred with clothes and arms, and made a very splendid and glittering show, and of which the Assyrian monarch gloried; this army the Jews say was destroyed by fire, and that the bodies of the men were burnt, and their clothes untouched; but Jarchi interprets this glory of their garments, which give a man glory, and says these were burnt; the Targum calls them their vessels of glory; perhaps meaning their glittering arms, which were burnt along with them.
