I'd start with that question at the end of 39,
Ezekiel 39:27-29 KJV
27) When I have brought them again from the people, and gathered them out of their enemies' lands, and am sanctified in them in the sight of many nations;
28) Then shall they know that I am the LORD their God, which caused them to be led into captivity among the heathen: but I have gathered them unto their own land, and have left none of them any more there.
29) Neither will I hide my face any more from them: for I have poured out my spirit upon the house of Israel, saith the Lord GOD.
I understand this to speak of what Jesus returns, and the angels regather Israel to her promised land.
Then, for me, the next question is,
Ezekiel 39:15-17 KJV
15) And the passengers that pass through the land, when any seeth a man's bone, then shall he set up a sign by it, till the buriers have buried it in the valley of Hamongog.
16) And also the name of the city shall be Hamonah. Thus shall they cleanse the land.
17) And, thou son of man, thus saith the Lord GOD; Speak unto every feathered fowl, and to every beast of the field, Assemble yourselves, and come; gather yourselves on every side to my sacrifice that I do sacrifice for you, even a great sacrifice upon the mountains of Israel, that ye may eat flesh, and drink blood.
Verse 16 closes the previous prophecy, and verse 17 begins the next prophecy. The question is, Does the prophecy beginning in vs. 17 follow chronologically after the prophecy ending in verse 16?
The prophecy ending in verse 16 is the same started in chapter 38.
To your question, is this about modern Israel, there's only one timing statement given, 38:8, "in the latter years". It's universally acknowledged that this hasn't happened yet. There is the reference to Gog and Magog concerning the end of the millennial kingdom, but there are some issues with that being the same thing, particularly that 7 year clean up time.
Personally, I think this invasion will occur just before the 70th week begins. That chapter 38-38:16 describes a war at the beginning of the week, and chapter 39:17ff describes Armaggedon.
I think that the destruction of the invaders in Ezekiel 38 parallels the sounding of the first trumpet in Revelation 8.
Much love!
