Isaiah 30:31

31 The Assyrians will be terrified when they hear the Lord's voice and feel the force of his punishment.

Isaiah 30:31 Meaning and Commentary

Isaiah 30:31

For through the voice of the Lord shall the Assyrian be
beaten down
As anything is by a storm of thunder, lightning, hail, and rain: or "fear", or be "affrighted", as the Vulgate Latin and Arabic versions render it; Sennacherib, the Assyrian monarch, and that part of his army which escaped, though not destroyed by it, were put into the utmost consternation: this shows that the prophecy in the context refers to the overthrow of the Assyrian army by the angel, when besieging Jerusalem in Hezekiah's time; though the Assyrian is sometimes used for any enemy of God's people at other times, particularly antichrist, and especially the eastern antichrist, the Turk:

[which] smote with a rod;
other nations, particularly the Jews, whom the Assyrian is expressly said to smite with a rod; and because he was an instrument in God's hand for the chastising of that people, he is called the rod of his anger, ( Isaiah 10:5 Isaiah 10:24 ) but now he that smote shall be smitten himself; him whom God used as a rod to correct others, he will smite with his rod, for his own correction: for this may be understood of God, and be rendered thus, "with a rod, he", that is, God, "shall smite" the Assyrian, as before; so Aben Ezra and Kimchi. The Targum interprets the "rod" of dominion.

Isaiah 30:31 In-Context

29 But you, God's people, will be happy and sing as you do on the night of a sacred festival. You will be as happy as those who walk to the music of flutes on their way to the Temple of the Lord, the defender of Israel.
30 The Lord will let everyone hear his majestic voice and feel the force of his anger. There will be flames, cloudbursts, hailstones, and torrents of rain.
31 The Assyrians will be terrified when they hear the Lord's voice and feel the force of his punishment.
32 As the Lord strikes them again and again, his people will keep time with the music of drums and harps. God himself will fight against the Assyrians.
33 Long ago a place was prepared where a huge fire will burn the emperor of Assyria. It is deep and wide, and piled high with wood. The Lord will breathe out a stream of flame to set it on fire.
