The four gospels were written 100 years or more after Jesus was murdered for stirring up trouble with the Priests and Sanhedrin. The earliest, Mark, not Matthew, tried to make Jesus out to be the Christ the Jews had long awaited. But Jesus was nothing like the description of the Christ, so stories were pulled, cherry-picked, from the OT to convince the Jews that Jesus was indeed the One promised.

1. 'Born of a "virgin"- the Greek word used in Isaiah for "virgin" typically meant "young woman" and young women were expected to be virgins.

2. 'Of the House of David"- IF Mary was a virgin whom God impregnated then Jesus wasn't the son of Joseph, therefore not of the House of David and not the "Christ" for whom the Jews had long been waiting for. Which is why they didn't accept Jesus as anything more than what he was- a wandering wise man, of which there were many.

3. The "messiah" is a later addition to his story but there were numerous men in the OT called "messiahs" and not all of them were Hebrew but each of them 'saved' the Hebrews in one way or another. "Messiah' means one who saves, not Christ. Am I claiming that "Christ" doesn't exist? Not at all. I am saying that Christ is the Holy Spirit of God and that only God can save anyone's soul. And that Jesus was as close to God as any man has ever been and he said that seeking Heaven was, to paraphrase, a fool's errand. Heaven, in his words, comes from within (the heart) and is spread over the face of the earth.

And that all who turn to God and honestly seek Him is a son of God; no intermediary needed. And that's why the Priests were against him- he was damaging their self-claimed importance to finding God. Which puts the "Christian" church in the same position as those priests- an impediment to finding God.
