John Gill

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 Psa 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, Psa 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 Psa 57:1. Selah; on this word; see Gill on Psa 3:2. (z) "in abscondito", Pagninus, Montanus; "in occultum", Junius & Tremellius.
