Jamieson, Fausset and Brown on Isaiah 10:4

4. Without me--not having Me to "flee to" (Is 10:3).

bow down--Bereft of strength they shall fall; or else, they shall lie down fettered.

under ... under--rather, "among" (literally, "in the place of") [Horsley]. The "under" may be, however, explained, "trodden under the (feet of the) prisoners going into captivity," and "overwhelmed under the heaps of slain on the battlefield" [Maurer].

Is 10:5-34 and Is 11:12. Destruction of the Assyrians; Coming of Messiah; Hymn of Praise.

Is 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 Is 10:27).
