The Sages have said:

And the King Messiah will be revealed and all the nations of the world will gather around King Messiah, and the verse will be fulfilled, 'The root of Jesse which standeth as the peoples' ensign, unto it shall the nations seek, and his resting place shall be glory. (Isaiah 11:10)'

The Sages have said:

I may remark then, that our Rabbis with one voice accept and affirm the opinion that the prophet is speaking of the King Messiah, and we ourselves shall adhere to the same view.
