'Servant of God' in the Bible

The Lord God has given Me [His Servant] the tongue of disciples [as One who is taught],That I may know how to sustain the weary with a word.He awakens Me morning by morning,He awakens My ear to listen as a disciple [as One who is taught].

Just as many were astonished and appalled at you, My people,So His appearance was marred more than any manAnd His form [marred] more than the sons of men.

For He [the Servant of God] grew up before Him like a tender shoot (plant),And like a root out of dry ground;He has no stately form or majestic splendorThat we would look at Him,Nor [handsome] appearance that we would be attracted to Him.
