All those events of historical Israel being led into the Holy Land serve as a 'blueprint' for the future event of God's consuming fire, and gathering of His saints to His Zion.
     The LORD through Isaiah is comparing these past few verses of Isaiah 30 to those historical events of His Passover, and leading the children of Israel out of Egypt and then to the Promised Land.

 Look closely again at Exodus 15 within that song, beginning at Exodus 15:14 through 18 that is the second time of God leading His children to Zion. The particular Exodus 15:14-18 verses have not happened yet. They are for this time our Lord is speaking of here in Isaiah, when He will lead His children who accept His New Testament Passover Jesus Christ, back to the Promised Land, in final for the Eternity. Notice in Exodus 15:15 that the "dukes of Edom" and the inhabitants of Canaan are mentioned in place of Pharaoh and the Egyptians.

Ezekiel 38 & 39 Read All.

The chief prince of Meshech (Esau-Edom-Idumea-Rosh-of Russia) and his allies are the ones these "hailstones" of God's wrath are upon, and that is the battle of Hamongog which God fights for us during the consuming fire event. It is yet future at Christ's coming.

 See Jeremiah 23, Read All. for another parallel to this same event, which is still future to us, and occurs when Christ returns.

Isa 30:31      For through the voice of the LORD shall the Assyrian be beaten down, which smote with a rod.

     Remember that the historical Assyrian is a blueprint role for Satan in the latter days? (Isaiah 14). The king of Assyria was used as a rod of correction upon old Israel when they were rebellious against The LORD. Satan as the "dragon" of the Book of Revelation serves as that old role of the Assyrian, but for the latter day tribulation. The first tribulation is by Satan and his; the second tribulation is the cup of God's wrath upon the wicked. Those in Christ don't have to worry about either tribulation, because our Lord is with us through both of them.
     The "voice of the LORD" is His Spirit Which these past few Isaiah verses have been declaring, and also is That Two-Edged Sword of Christ.

 Rev.1:16. That Sword is how Satan is going to be defeated during the first tribulation by The Holy Spirit speaking through Christ's election, and then directly by Christ at His coming (2 Thess.2:8; Matt.24). Satan will then be thrown into prison for the duration of Christ's thousand years reign (Rev.20).

Isa 30:32      And in every place where the grounded staff shall pass, which the LORD shall lay upon him, it shall be with tabrets and harps: and in battles of shaking will He fight with it.

     This event signal the time when Satan's purpose for this second earthly age will be over, as he will be locked away in his prison of the pit (Rev.20). Read All.
     Many do not realize that our Heavenly Father allows Satan as a rod of correction to get the attention of the rebellious of all families upon the earth. This is why we have no need to be scared of him. When this event occurs, many will look over into the 'pit' at him and say...

Isa 14:16     They that see thee shall narrowly look upon thee, and consider thee, saying, "Is this the man that made the earth to tremble, that did shake kingdoms;
17    That made the world as a wilderness, and destroyed the cities thereof; that opened not the house of his prisoners?"

     Now back to Isaiah to complete this Chapter...

Isa 30:33     For Tophet is ordained of old; yea, for the king it is prepared; He hath made it deep and large: the pile thereof is fire and much wood; the breath of the LORD, like a stream of brimstone, doth kindle it.

     This word "Tophet" means 'a place of fire', and historically refers to the valley of Hinnom south of Jerusalem, the garbage pit that burned perpetually. The children of the valley of Hinnom
