Adam Clarke's Bible Commentary Verse 3. Praise ye him, sun and moon ] The meaning of this address and all others to inanimate nature, is this: Every work of God's hand partakes so much of his perfections, that it requires only to be studied and known, in order to show forth the manifold wisdom power, and goodness of the Creator.
Stars of light ] The brightest and most luminous stars: probably the planets may be especially intended.
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.
