Adam Clarke's Bible Commentary Verse 1. Praise ye the Lord from the heavens ] The Chaldee translates, "Praise the Lord, ye holy creatures from the heavens. Praise him, ye armies of supreme angels. Praise him, all ye angels who minister before him." µymh m min hashshamayim signifies whatever belongs to the heavens, all their inhabitants; as Årah m min haarets, ver. 7, signifies all that belongs to the earth, all its inhabitants and productions.
Matthew Henry Commentary
Verses 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 desir 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 an Redeemer of the universe.
