Tertullian

Shall it be granted possible for human ingenuity to summon a spirit into water, and, by the application of hands from above, to animate their union into one body with another spirit of so clear sound; and shall it not be possible for God, in the case of His own organ, to produce, by means of "holy hands," a sublime spiritual modulation? But this, as well as the former, is derived from the old sacramental rite in which Jacob blessed his grandsons, born of Joseph, Ephrem and Manasses; with his hands laid on them and interchanged, and indeed so transversely slanted one over the other, that, by delineating Christ, they even portended the future benediction into Christ.
