Yes, it is about the end time also, but its a double entendre and has to be. If God gives a prophesy and it happened via the Assyrian's and it changed two kingdoms unto one, that is when God's prophesy came true, earlier in Ezekiel 37 we saw that one day Israel (Dry Bones) will will see their state of being changed, from Dead Dry Bones into sinew, but with no breath (holy spirit) in them, so yes, God brings Israel back into he land but God also led the into captivity, and called them dry bones, and a forsaken people, Paul says in Romans 11 that All Israel will be saved. And in Deuteronomy 30 God prophesied Israel would be led into captivity, then brought back into the land.
Deuteronomy 30:1 And it shall come to pass, when all these things are come upon thee, the blessing and the curse, which I have set before thee, and thou shalt call them to mind among all the nations, whither the Lord thy God hath driven thee, (Israel's Diaspora)
2 And shalt return unto the Lord thy God, and shalt obey his voice according to all that I command thee this day, thou and thy children, with all thine heart, and with all thy soul; 3 That then the Lord thy God will turn thy captivity, and have compassion upon thee, and will return and gather thee from all the nations, whither the Lord thy God hath scattered thee.
4 If any of thine be driven out unto the outmost parts of heaven, from thence will the Lord thy God gather thee, and from thence will he fetch thee:
5 And the Lord thy God will bring thee into the land which thy fathers possessed, and thou shalt possess it; and he will do thee good, and multiply thee above thy fathers.
We know the Diaspora was Israel, not just Jews, Jesus even stated he came for the Lost Sheep of Israel, which meat Israel were in the land up unto 70 AD. So, the prophesy of turning the land into One Nation again happened after/during the Assyrian siege, and has never changed right? Even though Jesus the son of David as per his lineage, will rule over Israel for the 1000 year Kingdom Age, the one nation switch only happens over 2500 years ago, if there has never been two nations since, it had to happen over 2500 years ago. Yes, Jesus is a part of the prophetic end, but that more or less means Jesus, the Son of David, will rule over that ONE NATION at the very end.
