Some Jewish Sects I believe,
The Messiah will come from Jerusalem and establish the Jews supremacy over the world aka the Kingdom of Heaven.
Emet Ve-Emunah, the Conservative movement's statement of principles, states the following:
Since no one can say for certain what will happen "in the days to come" each of us is free to fashion personal speculative visions ... Though some of us accept these speculations as literally true, many of us understand them as elaborate metaphors ... For the world community we dream of an age when warfare will be abolished, when justice and compassion will be the axioms of interpersonal and international relationships and when, in Isaiah's words (11:9) "...the land shall be filled with the knowledge of the Lord as the waters cover the sea." For our people, we dream of the ingathering of all Jews to Zion where we can again be masters of our destiny and express our distinctive genius in every area of our national life.... We affirm Isaiah's prophecy (2:3) that "...Torah shall come forth from Zion, the word of the Lord from Jerusalem. ... We do not know when the Messiah will come, nor whether he will be a charismatic human figure or is a symbol of the redemption of humankind from the evils of the world. Through the doctrine of a messianic figure, Judaism teaches us that every individual human being must live as if he or she, individually, has the responsibility to bring about the messianic age. Beyond that, we echo the words of Maimonides based on the prophet Habakkuk (2:3) that though he may tarry, yet do we wait for him each day
Some Christians believe if all the Jews is in Jerusalem, Jesus will show up.
This explains the Anti-Semitic yet Pro Zionist positions for some of them
It's an interesting prophecy regardless.
All strands agree though we're in the end times and Jerusalem will be something significant
