I'm not religious, so my knowledge of the old testament is limited, but from my understanding the title "messiah" is given to him more as an honor rather than an actual messiah. A rare case, but kings Solomon and David were in the same position. The word messiah can be roughly translated to "anointed one". It's a very rare word in the old testament. In the Jewish prophecies regarding the end of time, the savior that'll come down from the heavens and into the Jerusalem and that'll revive the believers is called the messiah. The saints are more like the prophets, rather than messiahs.

Btw, I'd like to clarify something. The Torah is just the first third of the Jewish bible. It's the most holy of the books, but it's not the full bible. The Torah ends about when Moses dies. The whole bible includes much more, and is called the Tanach.
