CLAIM: Jesus will wage war against the kings of the earth at the time of His Second Coming. Jesus will march up through Edom (modern day Jordan) on His way to Jerusalem. John makes reference to this passage in Revelation 19:11-21 by prophesying of Jesus going to war against the kings of the earth.
Transitionary, but looks back at events now fulfilled, but not yet at the time of the prophet.
Much of this is a prayer and praise relating various things, yet is in between two forward looking passages.. Indeed this passage opens with a review of Isaiah 56:19 of looking for one and finding no one, and achieving Righteousness Himself. It is a review in the midst of forward looking prophecies, and so is prophetic, and fits in the prophetic bearing, although it generally reflects back on previous circumstances, and is a prophetic crying out to God for the complete restoration.
However, the day of God’s Vengeance would have been the destruction of Jerusalem in 70AD, and so this, too, looks backwards, not forward.
