Psalms 135:21

Blessed be the Lord out of Zion,.... This, according to Aben Ezra, was the formula of blessing to be used by the houses of Israel, Aaron, and Levi, and all that feared God; or a direction to them in what manner they should bless him; and may both point out the persons that were to bless, and the place where; those that were inhabitants of Zion, where praise waited for the Lord, and was his due; and the blessings and benefits he was to be praised for, such as came out of Zion, strength from the Lord there, the rod of his strength, the word of the Gospel, and the Saviour himself;

which dwelleth at Jerusalem; in the temple there; and which distinguishes him from the idols of the Heathens before mentioned; and who dwells in the heavenly Jerusalem, in Gospel churches; and will dwell in the New Jerusalem, where his tabernacle will be with men,

Revelation 21:3;

praise ye the Lord; or "hallelujah"; and so the psalm ends as it begun, being from first to last an exhortation to praise.
