The voice of rejoicing and salvation [is] in the tabernacles of the righteous,.... In all the dwellings of good men, throughout the land of Israel, was heard nothing but the voice of joy, on account of David's accession to the throne; the deliverance of him from a persecuting Saul, and of them from his real administration; and the victories David obtained over all his enemies: for, "when the righteous are in authority, the people rejoice", Pr 29:2.
And still much more occasion is there of joy, in the dwelling places of the saints, though but cottages, and in the churches of God, the tabernacles of the most High, on account of the spiritual and eternal salvation Christ is the author of which joy is inwardly felt in the heart, and outwardly expressed by one saint to another; and in vocal prayer to God, and in singing his praises; which may be done in the houses of the saints, as well as in the house of God.
What this voice, or the righteous with their voice, expressed in each of their dwelling houses, is as follows; for the word "saying" may be supplied, and the words connected thus:[saying], the right hand of the Lord doth valiantly; or "acts powerfully" ; in helping and assisting David, in protecting and defending him, in raising him to the throne, and in giving him rest from all his enemies; and so in supporting the Messiah, his antitype, as man and Mediator, in his work and under his sufferings; in raising him from the dead, and exalting: him at his right hand; and which was done with his right hand, Ac 2:33.
Jarchi refers this joy here expressed to future times, the times of the Messiah: and in an ancient writing of the Jews the right hand of the Lord, three times mentioned in this verse and Ps 118:16, is interpreted of the Messiah, the sort of David.
