Many days and years shall ye be troubled; rather, in a year and days; i.e. "in less than two years." The object of the prophet is not to fix the duration of the trouble, but to mark the time of its commencement (comp.
Isaiah 29:1). Shall ye be troubled; rather, shall ye tremble, or shudder (so Deuteronomy 2:25; Psalms 77:18; Psalms 99:1; Isaiah 5:25; Isaiah 64:2; Jeremiah 33:9, etc.). Ye careless women; rather, ye confident ones.
The word is different from that employed in Isaiah 32:9 and Isaiah 32:11. The vintage shall fail; literally, has failed—"the perfect of prophetic certitude" (Cheyne). Some critics understand a literal failure, or destruction, of the vintage through the invasion of the Assyrians.
Others suggest a refer-once to Isaiah 5:4-7. The vineyard of the Lord (Judah) has utterly failed to bring forth grapes—there is no ingathering—therefore destruction shall fall upon it.
