'Comeliness' in the Bible

A voice says, “Call out [prophesy].”Then he answered, “What shall I call out?”[The voice answered:] All humanity is [as frail as] grass, and all that makes it attractive [its charm, its loveliness] is [momentary] like the flower of the field.

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.
