Isaiah 33:11

“Ye shall conceive chaff, ye shall bring forth stubble, &c.] Signifying that all the counsels, designs, and schemes, of the antichristian party, to continue themselves in their present state, and save themselves from ruin, as well as utterly to destroy the interest of Christ, would be weak, vain, and fruitless; their conceptions and actions, their purposes and attempts, would be alike; would be abortive, like chaff and stubble, and only serve as such for their own destruction: your breath [as] fire shall devour you; or, “your spirit”f656; your pride and haughtiness, in self praises, commendations, and glorying; your rage, wrath, and fury, against the saints; your blasphemy against God and…”

“Ye--the enemy. conceive chaff-- (Isa 26:18; Isa 59:4). your breath--rather, your own spirit of anger and ambition [MAURER], (Isa 30:28).”

“Ye shall conceive chaff - An address of God to the Assyrians. The figure is one that denotes that their counsels would be in vain. Chaff and stubble are used in the Scriptures, in contrast with grain, to denote anything which is not solid, nutritious, or substantial; then anything which is frivolous, useless, vain. A similar image occurs in Isaiah 26:18 (see the note on that place; compare Isaiah 59:4). Your breath as fire shall devour you - The word ‘breath’ here (רוח rûach, spirit) is evidently used in the sense of the Θυμός thumos, and denotes anger, as in Isaiah 30:28. It refers to the haughty and arrogant spirit of Sennacherib; the enraged and excited mind intent on victory and…”

“Stubble - Instead of solid corn. Your great hopes and designs, shall be utterly disappointed. Your breath - Your rage against my people shall bring ruin upon yourselves. Isaiah 33:12”

“33:11 In most passages, the Assyrians were turning other nations into worthless dry grass and stubble (see 17:13; 29:5; 40:24; 41:2). Here, ironically, they get a taste of their own medicine.”

“conceive: Isa 8:9, Isa 8:10, Isa 10:7-14, Isa 17:13, Isa 29:5-8, Isa 59:4; Job 15:35; Psa 2:1, Psa 7:14; Psa 83:5-18; Act 5:4; Jam 1:15 your: Isa 5:24, Isa 30:30-33, Isa 31:8, Isa 31:9, Isa 37:23-29; Nah 1:5-10 Isaiah 33:12”

“After the prophet has heard this from Jehovah, he knows how it will fare with them. He therefore cries out to them in triumph ( Isa 33:11), "Ye are pregnant with hay, ye bring forth stubble! Your snorting is the fire that will devour you." Their vain purpose to destroy Jerusalem comes to nothing; their burning wrath against Jerusalem becomes the fire of wrath, which consumes them (for chashash and qash, see at Isa 5:24). Isaiah 33:12”
