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.

“That the Lord was to be born of a virgin we know clearly; now we must show of what stock the virgin was. "The Lord swore to David a firm promise from which he will not withdraw: 'Your own offspring I will set on your throne.' " Again, "I will make his posterity endure forever and his throne as the days of heaven." Then, "Once by my holiness I have sworn; I will not be false to David: his posterity shall continue forever, and his throne shall be like the sun before me; like the moon, which remains forever." You see that the words concern Christ, not Solomon, for Solomon's throne did not endure as the sun. But if anyone should object that Christ did not sit on the wooden throne of David, let us produce that saying: "The scribes and Pharisees have sat on the chair of Moses." For this signifies not the chair of wood but the authority of his teaching.”

“"The Lord has made a faithful oath unto David, and He shall not repent" [Psalm 132:11]. What means, "has made an oath"? Hath confirmed a promise through Himself. What means, "He shall not repent"? He will not change. For God suffers not the pain of repentance, nor is He deceived in any matter, so that He would wish to correct that wherein He has erred. But as when a man repents of anything, he wishes to change what he has done; thus where you hear that God repents, look for an actual change. God does it differently from you, although He calls it by the name of repentance; for thou dost it, because you had erred; while He does it, because He avenges, or frees. He changed Saul's kingdom, when He repented, as it is said: and in the very passage where the Scripture says, "It repented Him;" it is said a little after, "for He is not a man that He should repent." When therefore He changes His works through His immutable counsel, He is said to repent on account of this very change, not of His counsel, but of His work. But He promised this so as not to change it. Just as this passage also says: "The Lord swore, and will not repent, You are a Priest for ever after the order of Melchizedec;" so also since this was promised so that it should not be changed, because it must needs happen and be permanent; he says, "The Lord has made a faithful oath unto David, and He shall not repent; Of the fruit of your body shall I set upon your seat." He might have said, "of the fruit of your loins," wherefore did He choose to say, "Of the fruit of your body"? Had He said that also, it would have been true; but He chose to say with a further meaning, Ex fructu ventris, because Christ was born of a woman without the man.”

“For the Lord hath chosen Zion,.... Not only to build upon it the temple in a literal sense, and for the place of his worship; but also for the seat of his majesty, and over which he has set his Son as King; and all this from the love he bears to Zion, which, in a figurative and spiritual sense, is his church; whom he has chosen to privileges, to grace and glory, and for his service and honour; see Psa 78:67; he hath desired it for his habitation; heaven is the habitation of his holiness and glory; Christ is his dwelling place, in whom all the fulness of the Godhead dwells bodily: yet his desire is to his church and people; his heart is set upon them, and upon their salvation; his delight is in them, and he takes pleasure in walking with them, and dwelling among them; they being built up an habitation for God through the Spirit; see Psa 68:16.”

“Make. Literally, “deceive him.” Hebrew, “will not turn from it,” the truth. (Berthier) — Thy. St. Cyprian and St. Hilary read, “my throne,” which belonged to the Lord, 1 Paralipomenon xxix. 23. (Calmet) — But it might also be styled David’s, as the promises were made to him. (Haydock) — Christ was born of the virgin’s womb, without having any man for his father. (St. Augustine) — This promise actually was fulfilled in Solomon, and in Christ, who would infallibly possess the throne, 2 Kings vii., and Acts ii. But Christ reigns over all. (Berthier) (Luke i. 32.) — St. Peter hence proves our Saviour’s resurrection, (Worthington) and power in the Church. (Haydock) — After the captivity, the royal power was not enjoyed by the family of David: which ought to have persuaded the Jews to acknowledge Christ and his eternal spiritual kingdom.”

“The "for the sake of David" is here set forth in detail. אמת in Psa 132:11 is not the accusative of the object, but an adverbial accusative. The first member of the verse closes with לדוד, which has the distinctive Pazer, which is preceded by Legarmeh as a sub-distinctive; then follows at the head of the second member אמת with Zinnor, then לא־ישׁוּב ממּנּה with Olewejored and its conjunctive Galgal, which regularly precedes after the sub-distinctive Zinnor. The suffix of ממּנּה refers to that which was affirmed by oath, as in Jer 4:28. Lineal descendants of David will Jahve place on the throne (לכסּא like לראשׁי in Psa 21:4) to him, i.e., so that they shall follow his as possessors of the throne. David's children shall for ever (which has been finally fulfilled in Christ) sit לכסּא to him (cf. Jer 9:5; Jer 36:7). Thus has Jahve promised, and expects in return from the sons of David the observance of His Law. Instead of עדתי זוּ it is pointed עדתי זו. In Hahn's edition עדתי has Mercha in the penult. (cf. the retreat of the tone in זה אדני, Dan 10:17), and in Baer's edition the still better attested reading Mahpach instead of the counter-tone Metheg, and Mercha on the ultima. It is not plural with a singular suffix (cf. Deu 28:59, Ges. 91, 3), but, as זו = זאת indicates, the singular for עדוּתי, like תּחנתי for תּחנוּתי in Kg2 6:8; and signifies the revelation of God as an attestation of His will. אלמּדם has Mercha mahpach., זו Rebia parvum, and עדתי Mercha; and according to the interpunction it would have to be rendered: "and My self-attestation there" (vid., on Psa 9:16), but zow is relative: My self-attestation (revelation), which I teach them. The divine words extend to the end of Psa 132:12. The hypotheses with אם, as the fulfilment in history shows, were conditions of the continuity of the Davidic succession; not, however - because human unfaithfulness does not annul the faithfulness of God - of the endlessness of the Davidic throne. In Psa 132:13 the poet states the ground of such promissory mercy. It is based on the universal mercy of the election of Jerusalem. אוּהּ has He mappic. like ענּה in Deu 22:29, or the stroke of Raphe (Ew. 247, d), although the suffix is not absolutely necessary. In the following strophe the purport of the election of Jerusalem is also unfolded in Jahve's own words.”
