29:1-8 Ariel may signify the altar of burnt-offerings. Let Jerusalem know that outward religious services will not make men free from judgements. Hypocrites never can please God, nor make their peace with him. God had often and long, by a host of angels, encamped round about Jerusalem for protection and deliverance; but now he fought against it. Proud looks and proud language shall be brought down by humbling providences. The destruction of Jerusalem's enemies is foretold. The army of Sennacherib went as a dream; and thus the multitudes, that through successive ages fight against God's altar and worship, shall fall. Speedily will sinners awake from their soothing dreams in the pains of hell.

heaviness … sorrow—rather, preserving the Hebrew paronomasia, "groaning" and "moaning."

as Ariel—either, "the city shall be as a lion of God," that is, it shall emerge from its dangers unvanquished; or "it shall be as the altar of burnt offering," consuming with fire the besiegers (Isa 29:6; Isa 30:30; 31:9; Le 10:2); or best, as Isa 29:3 continues the threat, and the promise of deliverance does not come till Isa 29:4, "it shall be like a hearth of burning," that is, a scene of devastation by fire [G. V. Smith]. The prophecy, probably, contemplates ultimately, besides the affliction and deliverance in Sennacherib's time, the destruction of Jerusalem by Rome, the dispersion of the Jews, their restoration, the destruction of the enemies that besiege the city (Zec 14:2), and the final glory of Israel (Isa 29:17-24).
