Aren’t we quibbling about the in gathering of the tribes of Israel v the in gathering of the tribe of Judah, as it is all but impossible - or at least very difficult - to separate today’s Jews into tribes? What we do know is that Jews from all corners of the world have relocated to Israel and that to me is a “gathering.”
But Jews do not include all of Israel, only the two tribes of Judah and Benjamin that comprised the southern kingdom of Judah after the breakaway of the ten northern tribes who formed their own kingdom under the name of Israel.
‘Jews’ are actually B’nei Yisrael (Sons of Israel) officially. The term Jew is a kind of nickname, unless it means of the tribe of Judah.
I’m unaware of any reference in the Jewish Bible to the ingathering of Yehudim to the exclusion of other tribes.
