Verse 5. - Let them praise the Name of the Lord. Frequent changes of person, when no doubt can arise as to the meaning, are a sort of Hebrew idiom. They give liveliness and variety. For he commanded, and they were created (Genesis 1:3, 6, 9, 11, 14, 15, etc.). All creation sprang into being at the word of God (Psalm 33:8).

148:1-6 We, in this dark and sinful world, know little of the heavenly world of light. But we know that there is above us a world of blessed angels. They are always praising God, therefore the psalmist shows his desire that God may be praised in the best manner; also we show that we have communion with spirits above, who are still praising him. The heavens, with all contained in them, declare the glory of God. They call on us, that both by word and deed, we glorify with them the Creator and Redeemer of the universe.Let them praise the name of the Lord,.... Set forth the glory of the nature and perfections of God, and celebrate the praise of them; even all celestial creatures, the angels, the hosts of heaven, the sun, moon, and stars; the heavens, and the haven of heavens, and the waters above them; and that for the following reasons;

for he commanded, and they were created; they are all his creatures, and therefore should praise him: he is the "Father of spirits", of angelic spirits, as well as the spirits of men; and the "Father of lights", of all the luminaries of the heavens; and he has made the heavens themselves, and all their hosts, and the firmament dividing the waters above and below; and all this by an almighty "fiat", at a word of command; he spoke, and they came into being at once, Hebrews 12:9, James 1:17.
