The Zohar, Chapter “BeShalach (When Pharaoh Sent),” Item 311: The Creator is destined to revive all those kings that have afflicted Israel and Jerusalem: Hadrian, Lupinus, Nebuchadnezzar, Sennacherib, and all the other kings in the world. He will give them dominion as in the beginning, and the rest of the nations will gather with them and they will wage war on Jerusalem.
And the Creator will avenge them openly around Jerusalem, as it is written, “And this shall be the plague with which the Lord will strike all the peoples who have gone to war against Jerusalem.” … And this is written for the time when the Messiah comes; this song is an eternal song.
This is not talking about times, but about Surrounding Lights that come to us, giving us the sensation of time. Therefore, everything we will reveal in the future, in greater Aviut (thickness, coarseness) of desire, are heavier parts of Malchut such as Sennacherib, Nebuchadnezzar, and others that become revealed at the very end of all the corrections.
That is why it is called the “time” when the Messiah (redemption from egoism) comes, the time of the general correction, the result of all the corrections. This correction takes place by the Surrounding Lights (Ohr Makif) and Kelim (desires, Lev HaEven) that were impossible to correct until this time, and now they are corrected.
