I will abide in thy tabernacle for ever - This expresses the confident assurance that he would be restored to his home, and to the privileges of public worship. The word forever here means perpetually; that is, his permanent home would be there, or he would dwell with God who dwelt in the tabernacle. The word "tabernacle" refers to the sacred tent which was erected for the worship of God, within which were the ark, the tables of the law, the table of showbread, etc. In the innermost part of that tent - the holy of holies - the symbol of the divine presence rested on the mercy-seat or cover of the ark of the covenant. David regarded it as a great privilege to abide near that sacred tent; near to the place of; public worship; near to the place where God was supposed to dwell. See Psalm 23:6, note; Psalm 26:8, note; Psalm 27:4, note. It is possible that his mind looked beyond the tabernacle on earth to an eternal residence in the very presence of God; to his being admitted into his own sacred abode in heaven.
I will trust in the covert of thy wings - Margin, Make my refuge. See the notes at Psalm 17:8. Compare Psalm 36:7; Psalm 57:1. The idea is, that he would seek and find protection in God - as young birds do under the outstretched wings of the parent bird.

I will abide in thy tabernacle - The greater portion of those Psalm which were composed during and after the captivity, says Calmet, had Levites and priests for their authors. Hence we find the ardent desire so frequently expressed of seeing the temple; of praising God there; of spending their lives in that place, performing the functions of their sacred office. There I shall sojourn; - there I shall dwell, - be at rest, - be in safety, - be covered with thy wings, as a bird in its nest is covered with the wings of its mother. These simple comparisons, drawn from rural affairs and ordinary occurrences, are more pleasing and consolatory in the circumstances in question, than allegories derived from subjects the most noble and sublime.

I will abide in thy tabernacle for ever,.... Under the protection of the Lord, as in a shepherd's tent, or as in one belonging to a general of an army, where are fulness and safety; See Gill on Psalm 27:5; or else the tabernacle of the congregation is meant; the house of God, the place of divine and public worship, where he desired and determined always to continue, Psalm 23:6; or else the tabernacle which was prefigured by that below, where he knew he should dwell to all eternity. Kimchi, by "for ever", understands a long time; and Jarchi explains it both of this world and of the world to come; which is true, understanding the tabernacle of the church below, and the church above;
I will trust in the covert of thy wings. Or, "in" or "into the secret of thy wings" (z); this he determined to make his refuge for the present time, and while in this world; See Gill on Psalm 57:1.
Selah; on this word; see Gill on Psalm 3:2.
(z) "in abscondito", Pagninus, Montanus; "in occultum", Junius & Tremellius.

I will abide--So I desire to do (compare Psalm 23:6).
trust in the covert, &c.--make my refuge, in the shadow (compare Psalm 17:8; Psalm 36:7).

I will - I shall, I doubt not, be restored to the tabernacle, and worship thee there all my days.
