Although there do exist Ethiopian Jews, Jesus' Semitic ancestry is traced in detail in the Bible all the way back to Abraham.  His mother, Mary, and step-father, Joseph, were required to return to Bethlehem in Judea, their place of origin, to register for the Roman census, and there Jesus was born. The Semites as a whole are slightly darker than Europeans but by no means as dark as the Cushites of South India or black Africa,  the "people of colour".  Jesus likely spoke Aramaic but he spoke Hebrew also.  He read the Hebrew Scriptures in the Synagogue and attributed the fulfilled prophecies in Isaiah to himself. Jesus' Jewish Judean descent is indisputable.
