While it is not known precisely when this fulfillment might occur, we can look to the recent past of the paragraph above concerning Psalm 83 to see that Iran did not play a role of belligerence and armorer of Israel enemies in the final fulfillment of the Psalm 83 war that it is currently casting itself in. There is a reason why Asaph did not itemize Persian participation in the Psalm 83 scenario. In sum, by the time Ezekiel 38/39 comes to fulfillment, Iran is a lesser military power that it is in late 2014, but Iran is not so weak that it cannot participate in the Ezekiel 38/39 attempt by Gog of Magog's confederation of forces invasion. This indicates the Jeremiah 49:34-39 in another prophecy of the end-times prophecies which goes through a process of literal fulfillment, not unlike Psalm 83 which is now in its 66th year of fulfillment process. We'll come back to this shortly.
At this point I will put a few key prophecies in a comparative spotlight. The prophets Jeremiah and Ezekiel reiterate key points of the same prophetic word given to them by the Lord. I have often searched for Scripture to parallel what is written in Ezekiel 36-39. I believe that parallel exists in Jeremiah 30:1-7 regarding the restoration of Israel and Judah to the land and a point blank reference which ties this restoration directly to the time of Jacobs trouble (i.e. the final 42-months of the Megas Thlipsis). In this set of verses we see a period of time that literally holds within its context a minimum of 1947-48 to at least two and one half decades into the 21st century (according to the generational template of Psalm 90:10). Again, a process of fulfillment is maintained in the plain text of the prophecy.
Then at Jeremiah 30:10b there is something that should be very familiar to all students of prophecy: "Jacob shall return, have rest and be quiet, and no one shall make him afraid." Compare this with Ezekiel 38:11 which says: "You will say, ‘I will go up against a land of unwalled villages; I will go to a peaceful people, who dwell safely, all of them dwelling without walls, and having neither bars nor gates’" That these are things of the 'last days' is beyond question as Jeremiah writes, "In the latter days you will consider it."
Jeremiah 30:16 reads, "Therefore all those who devour you shall be devoured; and all your adversaries, every one of them, shall go into captivity; those who plunder you shall become plunder, and all who prey upon you I will make a prey." Turning immediately to Ezekiel 39:10b the identical judgment is pronounced: "...Israel...will plunder those who plundered them, and pillage those who pillaged them,” says the Lord God."
Another prophetic parallel is found between Jeremiah 31:33-34, where it is written, "But this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My law in their minds, and write it on their hearts; and I will be their God, and they shall be My people. No more shall every man teach his neighbor, and every man his brother, saying, ‘Know the Lord,’ for they all shall know Me, from the least of them to the greatest of them, says the Lord. For I will forgive their iniquity, and their sin I will remember no more.”" This is clearly a direct reference to what the Lord says in Ezekiel 39:29, "And I will not hide My face from them anymore; for I shall have poured out My Spirit on the house of Israel,’ says the Lord God."
Is there any doubt these things are specifically the Lord God's dealings with Israel that will be occurring during the 70th Week, the purpose of which the angel Gabriel informed of Daniel by saying:
"Seventy weeks are determined
For your people and for your holy city,
To finish the transgression,
To make an end of sins,
To make reconciliation for iniquity,
To bring in everlasting righteousness,
To seal up vision and prophecy,
And to anoint the Most Holy."
Let me ask a question here. Are there two invasions of Israel in the last days? Is Daniel 11:40 a different end time war than the one Ezekiel prophecies about with enemies coming from both the north and south of Israel? If so, then during what period of time would Israel have men set aside to mark and bury the dead in the Valley of the Passengers/Hamonah east of the Dead Sea or be burning the enemy weaponry for the subsequent seven years?
Are there two invasions of Israel in the last days? That depends on some specifics, such as if at the time of Daniel 11:40 the Antichrist in Israel with power and authority at the start of the 70th Week. It occurs to me that for the literal fulfillment of John 5:43 his physical presence in Israel would appear to be a necessity. After all, it is this impostor of Moshiach ben David's 7-year covenant that Israel will accept in their misguided belief that he will be Moshiach ben David. I think the covenant he makes with the expanded great power that Israel will be at that time is a 7-year ‘partnership for peace’ between the Antichrist’s EU/NATO and Israel.
The start of the 70th Week is precisely 42 months prior to the Abomination of Desolation. It should be obvious that those 42 months amounts to a very short, finite amount of time; just enough for one great world war centered in the Middle East around Israel, but not two. I have come to think that these Scriptures indicate the Magog Confederation invasion occurs when Israel is living in a false sense of peace and security during the first 42 months of the 70th Week (the Thlipsis). God supernaturally destroys five-sixths of those enemies and send fire upon Magog Confederation's homelands and those dwelling securely in the coastlands. However, Antichrist is there with his False Prophet and all the attendant signs and lying wonders to usurp full credit of the miraculous defeat of the Magog Confederation's forces. And the people will believe this lie, as can be seen in the great overview of this period given to us by Paul in 2 Thessalonians 2:1-11, with particular respect to verse 11.
Then there's the second 42 months of the 70th Week, the Megas Thlipsis, and I believe Daniel 11: 41-45 are a brief overview of that period of time, with verse 44 directly related to the gathering Antichrist's forces at Harmagedōn (a/k/a Armageddon) to square off against a remnant army from the north and the approaching massive army of the kings of the east (image at the top) for whom the Euphrates River has been prepared for their passing over. But instead of fighting each other these forces square off to wage war upon Jesus Christ and His Saints at the Second Coming.
Addendum: An Eschatological Clarification
Daniel chapter 10 and 11 are the angel Gabriel's instructive narrative to the prophet Daniel of world events - primarily warfare and conflicts waged by European kings and their kingdoms in the Middle East across a great span of time totaling 27 centuries (6th century BC to the 21st century AD).
These two chapters are an indispensable key to unlocking and understanding 'last days' events; primarily leaders, battles and wars, and the future of Israel across this great expanse of time to the 'last days'.
The prelude to this entire narrative (Daniel 10:1-9) by the angel Gabriel occurs when Daniel is lying beside the Tigris (Hiddekel) River, in present-day Iraq which was at that time under the control of the Medo-Persian Empire (the second great world empire) and Daniel has an incredible vision of Gabriel in all of his angelic glory.
Gabriel begins the narrative by relating to Daniel how there are angelic contests involving Gabriel and Michael against other angelic beings which determine which kingdoms on the earth rise and which fall.
Gabriel begins this narrative be describing when the rise of the Macedonian-Greek king Alexander the Great (Alexander III of Macedon) and his world empire would occur (the third great world empire).
From Alexander the narrative of Gabriel traces a bloodline, a genetic lineage of kings to the forerunner of the Antichrist, Antiochus IV Epiphanes. Antiochus wars against the Macedonian-Greek kings of Ptolemaic Egypt are vividly described, as is his all important encounter in 168-67 BC with the rising fourth great world empire, the Roman Empire. The details of this are found in Daniel 11:29-31.
There is a seamless transition in Daniel 11 between the forerunner Antichrist Antiochus IV Epiphanes and the future Antichrist of Israel's 70th Week. This evokes the bloodline, a direct genetic link between the two. I believe this transition, a literal leap forward in time of more than 2,100 years plus a generation (this generation) occurs in the empty space between verses 35 and 36 of Daniel 11.
In Daniel 36 through 39 the angel Gabriel foretells the coming Antichrist's exploits in the near future and his rise to power, his takeover of entire nations at the start of the 70th Week.
Daniel 11:40 therefore is a battle which occurs during the early part of the 70th Week. I think this could well be the same battle as the Lord had Ezekiel prophesy about in chapters 38 and 39.
Then in Daniel 11:41-43 there's the European Antichrist's retaliatory military campaign of conquest throughout the eastern Mediterranean region.
Finally, Gabriel ends the narrative at verse 44 in what I believe is the intelligence report Antichrist receives informing him of the approach of massive armies - a remnant army from the north and the army of the kings of the East heading for the Euphrates River which has been dried up for their crossing. This is the stage setting for the final battle of Har Megadone (Armageddon) at the end of the 70th Week.
We all know what happens next.
