Psalms 66:2

Sing forth the honour of his name
Meaning not any particular names of the Messiah, such as in ( Isaiah 9:6 ) ( 7:14 ) ; 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 ) ( Psalms 9:10 ) ( Proverbs 18:10 ) . 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.
