(2) Sing forth.--Literally, play on the harp.

Make his praise glorious.--So the LXX., but the construction is dubious. Literally, put glory his praise, meaning perhaps, in parallelism with the first clause, "make the Divine glory the subject of your praise." But the opening words of the next verse, "say unto God, how," &c, are so bald that a suspicion arises as to the arrangement of the text. Perhaps by bringing back the initial words of Psalm 66:3 we get the true sense, "ascribe glory (and) speak praise to God."

Verse 2. - Sing forth the honour of his Name; rather, the glory of his Name. Make his praise glorious; or, recognize his glory in your praise of him; i.e. do not merely thank him for his kindness to you personally, but magnify him for his greatness and majesty.

66:1-7 The holy church throughout all the world lifts up her voice, to laud that Name which is above every name, to make the praise of Jesus glorious, both by word and deed; that others may be led to glorify him also. But nothing can bring men to do this aright, unless his effectual grace create their hearts anew unto holiness; and in the redemption by the death of Christ, and the glorious deliverances it effects, are more wondrous works than Israel's deliverance from Egyptian bondage.Sing forth the honour of his name,.... Meaning not any particular names of the Messiah, such as in Isaiah 9:6; or his name "Jesus", a Saviour; though they are all honourable and glorious, and furnish out sufficient matter for a song: but rather that by which he was made known to the sons of men, his Gospel; see Acts 9:15. Which is a glorious Gospel; the truths of which may be expressed in a song of praise, to the honour and glory of Christ, and to the instruction and profit of men, Colossians 3:16. Or rather Christ himself is meant; his name often designs himself, Matthew 12:21. There that is due unto him, and ought to be given which is done when all divine perfections and works are ascribed to him, divine worship is paid him, and the glory of salvation given him; which may be done in psalms, hymns, and spiritual songs;

make his praise glorious: let the high praises of him be in your mouths; give him, the most excellent praise; praise him in the best manner. This is done when we sing his praise with grace in our hears in exercise; when we with one mind and mouth glorify him; and when we honour him, the Son, as we honour the Father.
