The Hebrew Bible doesn't recognize Jesus as the Messiah. The New Testament does which was solely written in Greek and not Hebrew. Christian Bibles take their lead from the Greek writings and manipulated some scriptures.
Christians, however, had a different set of questions than the Dead Sea sect, and so they found different texts to cite. Any texts that refer to a time of a future deliverance, or the coming of a future king, were fair game. So the suffering servant of Isaiah 53 becomes the suffering Jesus of the gospels. And Luke's quotation from Isaiah 61 becomes a reference to Jesus's ministry of healing and reconciliation. Yet in every case, as far as we can tell, the Christian reading comes after the fact. That is, they first believed in Jesus and then tried to find his life in Scripture. They then could shape their telling of stories about his life to fit the scriptures. This process may seem very circular, but given their assumptions -- namely, that Jesus is central to God's plan, that God spoke through prophets who might not understand their own words, and that the Bible was a cryptic puzzle needing solving -- this belief in prophecy and fulfillment is not incomprehensible. So Luke can have Jesus say, "Today this Scripture is fulfilled in your presence!" Jesus saw himself as the deliverer that the prophets had foreseen long before. When his followers drew the same conclusion, they could then retain the ancient Scriptures, transforming them into something new, a Christian Bible.

You're not making a lot of sense, here. "Christian Bibles" are composed of BOTH the Old Testament (aka the Tanakh, aka the Hebrew Bible) and the New Testament. The OT was written some time before Jesus was even born. Plus, you forget that, initially, the disciples themselves thought that Jesus was going to do what most Jews were hoping that the Messiah would do: liberate Israel from Roman rule (in fact, we have the mothers of two of Jesus' disciples, politicking to get their sons positions in what-they-think-will-be Jesus' earthly kingdom).
Jesus did NOT free Israel from Roman domination. And, as mentioned elsewhere, the disciples saw him tortured and crucified. But, to once again use a quote from Dr. N.T. Wright,
"Since everyone knew that a crucified Messiah was a failed Messiah, the only thing that explained why they said Jesus was the Messiah is that they believed that He'd been bodily raised from the dead." Or, as Wright also stated, the disciples didn't get another Messiah, after Jesus had been crucified. It was after the Resurrection, that they finally got it.
Plus, Luke records that Simeon, and the prophetess, Anna, saw Jesus as a 6-week old baby and declared that He was whom the prophets (from the OT/Tanakh) foretold. Simeon had waited his whole priestly life to see the Messiah and stated that he could die in peace, knowing that the Lord had fulfilled what He (through the prophets) promised.
