His enemies I will clothe with confusion: but upon him will my sanctification flourish.

“For Joshua was to lead the people into the land of promise, not Moses. Now he called him an "angel," on account of the magnitude of the mighty deeds that he was to achieve (which mighty deeds Joshua the son of Nun did, and you yourselves have read about) and on account of his office of prophet announcing the divine will. Just as the Spirit, speaking in the person of the Father, calls the forerunner of Christ, John, a future "angel," through the prophet: "Behold, I sent my angel before your"—that is, Christ's—"face, who shall prepare your way before you." Nor is it a novel practice to the Holy Spirit to call those "angels" whom God has appointed as ministers of his power. For the same John is called not merely an "angel" of Christ but also a "lamp" shining before Christ. For David predicts, "I have prepared the lamp for my Christ"; and so Christ, coming "to fulfill the prophets," referred to him [John] [when speaking] to the Jews. "He was," he says, "the burning and shining lamp," being the one who not only prepared his ways in the desert" but, by pointing out "the Lamb of God," enlightened the minds of people by his proclaiming, so that they understood him to be that Lamb whom Moses was accustomed to announce as destined to suffer.”

“We speak to your charity in the house of God about what the present Psalm has reminded us. Who is it that says: I have prepared a lamp for my Christ. His enemies I will clothe with shame; but upon him my sanctification shall flourish; and what is that lamp which he has prepared for his Christ; and who are the enemies of his Christ, whom he clothes with shame through that lamp; and what is his sanctification, who prepared a lamp for his Christ, which will flourish upon his Christ. In all these words, it seems clear and open that he says here: For my Christ; for nothing else is to be understood than Christ the Lord and our Savior. Therefore, when exploring, as God grants, the depth of this meaning, we find that God the Father says this. Therefore, God the Father, that is, the person of God the Father speaks through the Prophet: I have prepared a lamp for my Christ. However, it is not necessary to explain to Christians that the Son of God is also the Christ of God. Having found the person speaking, let us see what the lamp prepared by God the Father for Christ the Son is. The Lord himself speaks about John the Baptist: He was a burning and shining lamp, and you were willing to rejoice for a while in his light. Therefore, he called John a lamp, kindled from the source of light. To bear witness to the truth. For men lay in this blindness and in this infirmity of the inner eye, so that the sun of righteousness would be sought through the lamp. For if anyone had a clear eye of the heart, he would first gaze upon it, nor would he seek a lamp for its testimony. For when he had said about that lamp: You were willing to rejoice for a while in his light; but I, he says, have greater testimony than John. Therefore, a lamp was kindled for the weak in the night. And how did he kindle it? The Father says to his Christ the Son about John: Behold, I send my angel before you, who will prepare your way before you. He has prepared a lamp for his Christ.”

“My. Hebrew, “his diadem,” (S. Ser.[St. Jerome?]) or “consecration.” The glory of David was great, as a figure of Christ, to whom this more properly belongs. He is the king of ages, without sin, &c. (Calmet) Bible Text & Cross-references: A prayer for the fulfilling of the promise made to David. 1 A gradual canticle. O Lord, remember David, and all his meekness. 2 How he swore to the Lord, he vowed a vow to the God of Jacob. 3 *If I shall enter into the tabernacle of my house: if I shall go up into the bed wherein I lie: 4 If I shall give sleep to my eyes, or slumber to my eye-lids, 5 Or rest to my temples: until I find out a place for the Lord, a tabernacle for the God of Jacob. 6 Behold we have heard of it in Ephrata: we have found it in the fields of the wood. 7 We will go into his tabernacle: we will adore in the place where his feet stood. 8 *Arise, O Lord, into thy resting place: thou and the ark, which thou hast sanctified. 9 Let thy priests be clothed with justice: and let thy saints rejoice. 10 For thy servant David’s sake, turn not away the face of thy anointed. 11 The Lord hath sworn truth to David, and he will not make it void: *of the fruit of thy womb I will set upon thy throne. 12 If thy children will keep thy covenant, and these my testimonies, which I shall teach them: Their children also for evermore shall sit upon thy throne. 13 For the Lord hath chosen Sion: he hath chosen it for his dwelling. 14 This is my rest for ever and ever: here will I dwell, for I have chosen it. 15 Blessing, I will bless her widow: I will satisfy her poor with bread. 16 I will clothe her priests with salvation: and her saints shall rejoice with exceedingly great joy. 17 *There will I bring forth a horn to David: I have prepared a lamp for my anointed. 18 His enemies I will clothe with confusion: but upon him shall my sanctification flourish.”
