[af_vet_1981]

Jesus never called the Lost Ten Tribes by the name Judah.

I cannot think of a single scripture where he spoke of the Ten Tribes, lost or otherwise. He did speak of twelve tribes ...

And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel.

Catholic chapter nineteen, Protestant verse twenty eight,
as authorized, but not authored, but King James

That verse is prophecy meant for after the 12 tribes are reunited.

Correct, of Israel. Jacob was Israel, per Genesis 32:28. Judah, the patriarch of the Jews, was Jacob’s fourth son, by Leah.
