O praise the Lord, all ye nations,.... The Lord having chosen, and Christ having redeemed, some out of every kindred, tongue, people, and nation; and the Gospel being sent and preached to all nations, and some of each being called and converted by the Spirit of God; they are excited to praise the Lord, Jehovah, Father, Son and Spirit, for their several acts of divine grace and kindness towards them, in choosing, redeeming, and sanctifying them; and in favouring them with the Gospel, and the ordinances of it, and with his gracious presence in them; and in supplying them with his grace, and giving them a right unto and meetness for eternal glory; for all which praise should be given to the Lord; praise him, all ye people; ye people of God in the several nations of the world; not the Jews only, but the Gentiles also: the same thing is repeated in different words, for the greater certainty and confirmation of it; that this should be, the work and exercise of the Gentiles in Gospel times, and expresses eagerness and vehemence to stir them up to it. A different word is here used for "praise" than in the former clause; and which is more frequently used in the Chaldee, Syriac, Arabic, and Ethiopic languages; and signifies the celebration of the praises of God with a high voice.
