Sing forth the glory of his name: Make his praise glorious.
Sing forth the honour of his name. The noise is to be modulated with tune and time, and fashioned into singing, for we adore the God of order and harmony. The honour of God should be our subject, and to honour him our object when we sing. To give glory to God is but to restore to him his own.
The psalmist celebrates one deliverance, but means it as proof of God's constant mercy to His people through all ages. His point is comfort: our subjection to enemies has been the furnace proving us as silver, and God's hearing of the faithful proves His acceptance of them alone, not the wicked.

Commenting on Psalm 66:1-20
Sing forth the honour of his name,.... Meaning not any particular names of the Messiah, such as in Isa 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 Act 9:15.
