Tertullian

“ For (his blessing) interprets spiritually thus: “Simeon and Levi perfected iniquity out of their sect,” [23] —whereby, to wit, they persecuted Christ: “into their counsel come not my soul! and upon their station rest not my heart! because in their indignation they slew men”—that is, prophets—“and in their concupiscence they hamstrung a bull!” [24] —that is, Christ, whom—after the slaughter of prophets—they slew, and exhausted their savagery by transfixing His sinews with nails. Else it is idle if, after the murder already committed by them, he upbraids others, and not them, with butchery. ”

“ For even in a ship’s yard—which is part of a cross—this is the name by which the extremities are called; while the central pole of the mast is a “unicorn.” By this power, in fact, of the cross, and in this manner horned, He does now, on the one hand, “toss” universal nations through faith, wafting them away from earth to heaven; and will one day, on the other, “toss” them through judgment, casting them down from heaven to earth.
He, again, will be the “bull” elsewhere too in the same scripture. [20] When Jacob pronounced a blessing on Simeon and Levi, he prophesies of the scribes and Pharisees ”

“ Similarly, again, Isaiah says: “For a child is born to us, and to us is given a son.” [34] What novelty is that, unless he is speaking of the “Son” of God?—and one is born to us the beginning of whose government has been made “on His shoulder.” ”

“ For, the cause of the favour accorded Him being shown,—in return, to wit, for the injury of a death which had to be recompensed,—it is likewise shown that He, destined to attain these rewards because of death, was to attain them after death—of course after resurrection. For that which happened at His passion, that mid-day grew dark, the prophet Amos announces, saying, “And it shall be,” he says, “in that day, saith the Lord, the sun shall set at mid-day, and the day of light shall grow dark over the land: and I will convert your festive days into grief, and all your canticles into lamentation ”

“ He says, “my hands and feet” [40] —which is the peculiar atrocity of the cross; and again when He implores the aid of the Father, “Save me,” He says, “out of the mouth of the lion”—of course, of death—“and from the horn of the unicorns my humility,” [41] —from the ends, to wit, of the cross, as we have above shown; which cross neither David himself suffered, nor any of the kings of the Jews: that you may not think the passion of some other particular man is here prophesied than His who alone was so signally crucified by the People. ”

“ For he who then gazed upon that (cross) was freed from the bite of the serpents. [31]
Come, now, if you have read in the utterance of the prophet in the Psalms, “God hath reigned from the tree,” [32] I wait to hear what you understand thereby; for fear you may perhaps think some carpenter-king [33] is signified, and not Christ, who has reigned from that time onward when he overcame the death which ensued from His passion of “the tree.” ”
