In Psalm 110 …
… when do these events of judgment, as depicted in this Psalm, primarily take place?
These events take place in the following time frames:
During Jeremiah’s “Time of Jacob’s Trouble”, known also as Daniels’ “Time of the End” … which occur within “THE Tribulation”, mentioned by Messiah and depicted by John the Revelator in the Book of Revelation …
… but also at the time of the events (and thereafter), of Messiah’s coming to rule and reign with a rod of iron AND a staff of comfort.
