Charles Ellicott Commentary Psalms 104:1-4

"Bless Jehovah, O my soul. O Jehovah my God, thou art very great; Thou art clothed with honor and majesty: Who coverest thyself with light as with a garment; Who stretchest out the heavens like a curtain; Who layeth the beams of his chambers in the waters; Who maketh the clouds his chariot; Who walketh upon the wings of the wind; Who maketh winds his messengers; Flames of fire his ministers;" — Psalms 104:1-4 (ASV)

First and second days of Creation. Instead, however, of describing the creation of light, the poet makes a sublime approach to his theme by treating it as a symbol of the Divine majesty. It is the vesture of God, the tremulous curtain of His tent, whose supporting beams are based, not on the earth, but on those cloud-masses which form an upper ocean. This curtain is then, as it were, drawn aside for the exit of the Monarch attended by His throng of winged messengers.
