5 But the multitude of your foreign foes shall be like small dust, and the multitude of the ruthless like passing chaff. And in an instant, suddenly, 6 you will be visited by the Lord of hosts with thunder and with earthquake and great noise, with whirlwind and tempest, and the flame of a devouring fire. 7 And the multitude of all the nations that fight against Ariel, all that fight against her and her stronghold and distress her, shall be like a dream, a vision of the night. 8 As when a hungry man dreams he is eating and awakes with his hunger not satisfied, or as when a thirsty man dreams he is drinking and awakes faint, with his thirst not quenched, so shall the multitude of all the nations be that fight against Mount Zion.
Matthew Henry's Commentary on Isaiah 29:5-8
Commentary on Isaiah 29:1-8
(Read Isaiah 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.
