...as a Rabbi-acolyte. His master was Joshua Ben Prahya. The Jewish story is that his nonconformist viewes were not well taken by the Rabbinical establishment, and eventually, they expelled him over a trifle. He was on his way to Egypt with his master, and they stopped at an inn. He was accused of coveting the inn keeper, and his master dismissed him.

That has been a political mistakes, because he was then under no restrictions and could form his own group of followers and promote his ideas unchecked.

Anyway, I suppose this story could also be a myth written after his time, but I think the Jewish rabbinical establishment has little motivation of promoting the Jesus myth. After all, he was the cause of nothing but trouble for them. I heard this secondhand, though, so hold on to your skepticism if you wish.
