Praise ye the Lord,.... When he shall reign, as Kimchi connects this psalm with the preceding; the arguments used to engage men to this work are taken partly from the nature of it, as in the next clauses; and partly from what the Lord is and does, as in the following verses; for it is good to sing praises unto our God; it being agreeably to his revealed will, what he enjoins, approves of, and accepts, and is profitable to his people, as well as makes his glory; see Psa 92:1. Some render it, "because he is good", as in Psa 106:1; but the accents, and what follows, will not admit of this sense; for it is pleasant; to our God; with which the Septuagint, Vulgate Latin, Ethiopic, and Arabic versions, join this clause; the sacrifice of praise is more pleasing to the Lord than any ceremonial sacrifice, especially when offered from a grateful heart in the name of Christ, and with a view to his glory; and it is pleasant to saints themselves, when grace is in exercise, and they make melody in their hearts to the Lord; and praise is comely: is due to the Lord, and becomes his people to give it to him; it is but their reasonable service, and a beautiful and lovely sight it is to see the chosen, redeemed, and called of the Lamb, harping with their harps, and singing the song of redeeming love.
