This is my rest for ever. The same truth is here put into the mouth of God, to give it additional weight; and it is declared not to have been in vain that the Temple had been erected, since God would show effectually and by practical testimonies the delight which he had in the worship of his own appointment. God's resting, or talking up his habitation, are expressions which denote his being present with men in the manifestation of his power. Thus he dwelt in Zion, in the sense that there his people worshipped him according to the prescription of his law, and found besides the benefit of the service in his favorable answer to their requests. It was eventually seen, in a very striking manner, that this was the promise of an infallible God, whet, after the Temple had been overthrown, the altar cast down, and the whole frame of legal service interrupted, the glory of the Lord afterwards returned to it once more, and remained there up to the advent of Christ. We all know in what a wicked and shameful manner the Jews abused the divine promise which is here made, under the impression that it necessarily laid God under an obligation to favor them, taking occasion from if, in the pride of their hearts, to despise, and even cruelly persecute the Prophets. Luther on this account calls it "the bloody promise;" for, like all hypocrites who make God's holy name a covert for iniquity, they did not hesitate, when charged with the, worst, crimes, to insist that it was beyond the power of the Prophets to take from them privileges which God had bestowed. With them to assert that the Temple could be stripped of its glory, was equivalent to charging God with falsehood, and impeaching his faithfulness. Under the influence of this spirit of vain confidence they proceeded such inconceivable lengths in shedding innocent blood. Were the Devil of Rome armed with pretensions as splendid, what bounds would be set to its audacity? As it is, we see how fiercely, and with what bloody pride it arrogates the name of the Church, while outraging all religion, in open contempt of God and flagrant violation of humanity. But what of that? the hierarchy would otherwise fall, and this must stand, if Christ would not desert his spouse the Church! The refutation of such a plea is not far to seek. The Church is limited to no one place: now that the glory of the Lord shines through all the earth, his rest is where Christ and his members are. It is necessary that we rightly understand what the Psalmist says of the everlasting continuance of the Temple. The advent of Christ was "the time of reformation," and the figures of the former Testament, instead of being then proved or rendered vain, were substantiated, and received their fulfillment in him. If it be still objected that mount Zion is here spoken of as the everlasting residence of God, it is sufficient to answer that the whole world became an enlarged mount Zion upon the advent of Christ.

This is my rest for ever - My home; my permanent abode. I will no more remove from place to place - as when the ark was carried in the wilderness, and as it has been since; but Zion shall now be the fixed seat of religion. See the notes at Psalm 68:16.
Here will I dwell - Permanently; constantly.

This is my rest for ever - Here the Christian Church is most indubitably meant. This is God's place for ever. After this there never will be another dispensation; Christianity closes and completes all communications from heaven to earth. God has nothing greater to give to mankind on this side heaven; nor does man need any thing better; nor is his nature capable of any thing more excellent.

This [is] my rest for ever: here will I dwell; for I have (i) desired it.
(i) Meaning, for his own sake and not for the plentifulness of the place: for he promises to bless it, declaring before that it was barren.

This is my rest for ever,.... The rest of my majesty, as the Targum; the place of his rest: and this being for ever shows that not Mount Zion literally, nor the temple, are meant; but the church and people of God, in whom he rests in his love, and rejoices over with joy; who are the objects of his delight, and with whom he abides for ever; for this phrase is expressive of pleasure and delight, and of permanency and perpetuity;
here will I dwell, for I have desired it; not merely by his omnipresence, in which sense he dwells everywhere, both in heaven and in earth; nor only by his omnipotence, by which he upholds all creatures in their being, and so is present with them all; and they all live and move, and have their being, in him: but by his Spirit and grace reviving and refreshing the hearts of his people with his gracious presence; which is enjoyed in his house and ordinances, and makes them lovely and delightful; and may be expected there, since he has promised it, and it is so desirable and agreeable to himself to dwell there.

That choice is expressed in God's words, "I will sit" or "dwell," or sit enthroned. The joy of the people springs from the blessings of His grace, conferred through the medium of the priesthood.

Shiloh has been rejected (Psalm 78:60), for a time only was the sacred Ark in Bethel (Judges 20:27) and Mizpah (Judges 21:5), only somewhat over twenty years was it sheltered by the house of Abinadab in Kirjath-Jearim (1-Samuel 7:2), only three months by the house of Obed-Edom in Perez-uzzah (2-Samuel 6:11) - but Zion is Jahve's abiding dwelling-place, His own proper settlement, מנוּחה (as in Isaiah 11:10; Isaiah 66:1, and besides 1-Chronicles 28:2). In Zion, His chosen and beloved dwelling-place, Jahve blesses everything that belongs to her temporal need (צידהּ for זידתהּ, vid., on Psalm 27:5, note); so that her poor do not suffer want, for divine love loves the poor most especially. His second blessing refers to the priests, for by means of these He will keep up His intercourse with His people. He makes the priesthood of Zion a real institution of salvation: He clothes her priests with salvation, so that they do not merely bring it about instrumentally, but personally possess it, and their whole outward appearance is one which proclaims salvation. And to all her saints He gives cause and matter for high and lasting joy, by making Himself known also to the church, in which He has taken up His abode, in deeds of mercy (loving-kindness or grace). There (שׁם, Psalm 133:3) in Zion is indeed the kingship of promise, which cannot fail of fulfilment. He will cause a horn to shoot forth, He will prepare a lamp, for the house of David, which David here represents as being its ancestor and the anointed one of God reigning at that time; and all who hostilely rise up against David in his seed, He will cover with shame as with a garment (Job 8:22), and the crown consecrated by promise, which the seed of David wears, shall blossom like an unfading wreath. The horn is an emblem of defensive might and victorious dominion, and the lamp (נר, 2-Samuel 21:17, cf. ניר, 2-Chronicles 21:7, lxx λύχνον) an emblem of brilliant dignity and joyfulness. In view of Ezekiel 29:21, of the predictions concerning the Branch (zemach) in Isaiah 4:2; Jeremiah 23:5; Jeremiah 33:15; Zac 3:8; Zac 6:12 (cf. Hebrews 7:14), and of the fifteenth Beracha of the Shemone-Esre (the daily Jewish prayer consisting of eighteen benedictions): "make the branch (zemach) of David Thy servant to shoot forth speedily, and let his horn rise high by virtue of Thy salvation," - it is hardly to be doubted that the poet attached a Messianic meaning to this promise. With reference to our Psalm, Zacharias, the father of John the Baptist, changes that supplicatory beracha of his nation (Luke 1:68-70) into a praiseful one, joyfully anticipating the fulfilment that is at hand in Jesus.
