Jewish concepts of eschatology first appear in the book of Daniel which passed on into Christianity.
We know quite a lot about how the Book of Daniel came to be written. It was written about 164 B.C., probably by several authors. And its background was what was known as the Antiochan persecution of the Jews.
After Alexander the Great conquered that whole area of the Near East, he left behind him a number of successor kingdoms, one of which was based in Syria. It was known as the Seleucid dynasty, and one of the monarchs, a particularly nasty one, was called Antiochus Epiphanes IV. And he did exercise a very real tyranny over the Jews.
On the whole, these ancient Near Eastern empires didn't persecute people for their religion. They could be nasty to conquered peoples as conquered peoples, but they left their religion largely undisturbed. But not so this man, who desecrated the Temple and forbade all Jewish religious practices. The answer to this was that those Jews who wouldn't compromise in any way started a war, known as the Maccabean Revolt, and in the end won. And they defeated Antiochus, and reconsecrated the Temple, and it was during this war that the Book of Daniel was composed.
It wasn't, however, composed by the Maccabeans. Any idea that is was a kind of recruiting manifesto is now discredited. It wasn't that. It was simply a prophetic writing. Saying that we're going to defeat Antiochus and beyond that lies a world in which the Jews will be recognized as God's chosen people, and will really dominate in their turn.

Daniel is not about the future of the seven churches.. NO prophet ever wrote thousands of years into the future.
They were commentators not fortunetellers.
Jewish eschatology seems very different from Revelation to me.
For instance .. God and Magog invaded Syria-Palestine many years before the birth of Christ... and they did come swiftly like locusts on horseback.
Daniel's writings are not in Nivi'im (Prophets): they are in 'Ketuvim' (Writings) If you're talking Jewish eschatology, Daniel is less authoritative than any actual prophet.
And the KJV, for all its poetic beauty, is about the least accurate rendition of the Hebrew Bible into English.
