The scriptures I have are all the Gospels, but John in particular.
Every Old Testament Judge and King was a messiah, meaning an anointed one. Therefore, there have been many messiahs in Judaism. Note that in Judaism, first the Judges then the Kings were the ones in charge of worldly affairs. Therefore, when Jews lost to other nations and did not have an anointed Jewish king, they looked for their next Messiah (anointed king). It never occurred to them to look for a priest, prophet, or spiritual leader because these remained in Jewish culture.
According to the Gospels, people still acknowledged prophets in Jesus' day. However, after the advent of Christianity, Jewish Canon says that Malachi was the last Jewish prophet. I disagree with that on the basis that John the Baptist and Jesus both qualified as prophets. Remember Levites asking John-the-Baptist, "Are you The Prophet?"
There is so much we don't know and I have never been able to learn much about The Prophet. It seems that Moses spoke of him, as someone greater than he. Moses was known for teaching the Law to the Israelites, and Jesus is also known for teaching about the Law.
My point is that Messiah meant 'anointed' and Jesus was clearly anointed by God (Christian belief) to proclaim the Good News and to teach Repentance for the forgiveness of sins. However 'Messiah' also meant a world political ruler, and this is clearly what Jews meant when speaking of "The Messiah."
I do not believe that Moses foretold of someone in the Line of David because Moses was not only before David's time, he lived before the time of Kings. I believe Moses spoke not of a ruler but of The Prophet (meaning one who speaks for God) who would be greater than he. A prophet is someone to whom Moses could relate, someone who knew God spoke for Him. Jesus insisted this is what he was doing--speaking and acting as God directed him. He insisted he was One with God.
While there is nothing wrong in asking for a single verse or two, there is nothing particularly strong about using proof-texting. It usually lifts that specific verse out of context and it ignores all the verses. Another thing it does: Causes comments such as, "Sounds like work-based salvation..." which makes your own denominations sound like lazy do-nothings when it comes to serving God and our fellow-man. Scripture is clear: There is no such thing as work-based salvation is equally clear that we are to discern the will of God and serve Him--and we are to help our fellow-man.
All that being said...Paul used proof-texting of the Old Testament quite a lot himself--and I do not agree with all his 'proof-texts' either. Just because Paul used them does not turn them into something stronger than the original author(s) of those verses intended. They serve as analogies, and at some point analogies always fail. Not that analogies and proof-texts are useless, they are not, but we should always note the point at which they fail, too.
