I will break the Assyrian in my land. This is referred by some critics to the miraculous destruction of Sennacherib's army, and regarded as a proof that the scene, of that destruction was Judaea. But it is possible that a disaster to the forces of Sargon may be intended (see the comment on Isaiah 10:28-32).
His yoke shall depart from off them (comp. Isaiah 10:27). The Assyrian yoke, imposed by Tiglath-Pileser (2 Kings 16:7-10), and (according to his own inscriptions) again by Sargon, was thrown off by Hezekiah, who "rebelled against the King of Assyria, and served him not" (2 Kings 18:7).
It was this rebellion that provoked the expedition of Sennacherib, described in 2 Kings 18:13-16; and it may be this rejection of the yoke which is here prophesied.
