Don't you place the following events recorded in
Ezekiel 39:9-15, during the last 7 years, where a portion of those 7 years would be the great tribulation?
The Gog/Magog event takes place right before the the 7 years begin.
The last 1335 days of the 7 years are the great tribulation.
Gog/Magog, then the 7 years. Ezekiel 39:9-15, which is the burial of Gog's army, will take place for 7 months, following Gog/Magog.
Keep in mind that the exact number of days of the 7 years is not 2520 days, except for the understanding of the end times events, and to put them in order.
There will be at least one, maybe two, leap months that will take place over the course of the 7 years... but since we don't know exactly on a calendar when Gog/Magog takes place, nor the day the confirming of the covenant takes place, we cannot factor in the leap months.
The 7 months of Ezekiel 39:9-15 are the first 7 months of the 7 years. The last 1335 days of the 7 years will be the great tribulation.
Can you show via any passages in the NT, which you feel involve the last 7 years of human history, where anything remotely like
Ezekiel 39:9-15 is taking place during these final 7 years?
I don't use the term "human history". But if you want to say man's quasi independent rule over the nations, before the Kingdom of God becomes the ruling kingdom over the nations here on earth - then I am on board.
The answer to your question, though, is no for the 7 months, but yes for the 7 years.
In Revelation 12, the 7 years are the 1260 days first half, (the war in the second heaven + the remaining time, times, half time) the second half. The 7 heads have their crowns, indicating king 7, the little horn person will have come to power.
There is some teachings by the RAMBAM that the messiah will fight the battles of God in defending Israel. In Daniel 8:23, the little horn person "stands up" an idiom for prepares to go to war. In Daniel 8:9, the little horn heads south and east, from the territory of one of the break up kingdoms of Alexander, with a strong army.
Putting those things together, it appears as though prior to Gog/Magog, the little horn leader of the EU will stage the EU defense force (which they are in the process of building) in Greece as a deterrent.
It does not say whether or not, he engages Gog/Magog or not.
However, my view is that the Jews will view his intent as to standing up to fight to defend Israel. And when he enters the middle east, following Gog/Magog, to keep peace in the region and stability in the region, that will be enough for the Jews to embrace him as the messiah. The Jews, many of them expect the messiah to arrive following Gog/Magog, which they interpret Zechariah 14 as the same event, to begin the messianic age of peace and safety.
The person will be anointed the King of Israel, by the false prophet, then he will make the big speech from the temple mount, as Moses required of all future leaders of Israel, on a 7 year cycle, that God gave the land of Israel to the children of Israel as theirs forever. Deuteronomy 31:9-13
That's what begins the 7 years.
