Who is this Jew written about in the book of the prophet Zechariah?

Zechariah 8:23

This is what the LORD Almighty says:

“In those days ten men from all languages and nations will take firm hold of one Jew by the hem of his robe and say,

‘Let us go with you, because we have heard that God is with you.’ “

(end of scripture)

There are not many Jews who have fan`s all over the World. The only Jew who has followers in every city on the face of the Earth, is a Hebrew who was named Y´shua.

Translated into English, we call Him «Jesus».

If this Jew is not the man from this verse of the Tanakh, than who is He? And if Jesus is this “one Jew”, we better pay attention to His teachings.
