If being meek and lowly were a messianic prophecy then billions of people qualified to be the messiah.
A messianic prophecy must be something that only the messiah could fulfill (or it could only be fulfilled in his lifetime). True messianic prophecies are not applicable to billions of people -- they include world peace, global knowledge of G-d, and the return of all of the Jewish people to the land of Israel.
Did you notice that Jesus fulfilled none of those prophecies?
Y'shayahu / Isaiah 42:2 says nothing about anyone being meek and / or lowly. It says "He shall neither cry nor shall he raise [his voice]; and he shall not make his voice heard outside."
Jesus DID cry out on the cross.
Jesus DID raise his voice (whipping the money changers ring a bell?).
At any rate, the claimed prophecy is totally unsupported by the biblical passage.
Since Christians claim Jesus was G-d Himself how could he be considered lowly? Meek? This one fails at the start. . .
Matthew 11:28-30 has various translations some of which say Jesus was meek or lowly but others say gentle and humble (NIV) -- but in any case there is no such messianic prophecy that the messiah will be meek and lowly, and definitely not Y'shayahu / Isaiah 42:2.
