Tertullian

In him dwelt the fullness 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 has rested, according to Isaiah, "the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and piety, and of the fear of the Lord." Now to no man, except Christ, would this diversity of spiritual proofs suitably apply. He is indeed like a flower for the Spirit's grace, reckoned indeed of the stem of Jesse but thence to derive his descent through Mary.
