Tertullian

“ According to the same prophet, however, He is in bodily condition “a very worm, and no man; a reproach of men, and an outcast of the people.” [8] But no internal quality of such a kind does He announce as belonging to Him. In Him dwelt the fulness of the Spirit; therefore I acknowledge Him to be “the rod of the stem of Jesse.” His blooming flower shall be my Christ, upon whom hath rested, according to Isaiah, “the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of piety, and of the fear of the Lord.” ”

“ Isaiah comes to our help again: “We have announced (His way) before Him,” says he; “He is like a servant, [4] like a root in a dry ground; He hath no form nor comeliness; we saw Him, and He had neither form nor beauty; but His form was despised, marred above all men.” [5] Similarly the Father addressed the Son just before: “Inasmuch as many will be astonished at Thee, so also will Thy beauty be without glory from men.” ”

“ He can be none other than the Man who was foretold. It is right that His conduct [13] be investigated according to the rule of Scripture, distinguishable as it is unless I am mistaken, by the twofold operation of preaching [14] and of miracle. ”
