Psalm 104:3

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 layeth the beams of his chambers in the waters,.... Or "his upper rooms" {i}; one story over another being built by him in the heavens, Amos 9:6, the chambers where he resides; his courts, as the Targum; his palace and apartments, his presence chamber particularly, the floor and beams of them are the waters bound up in the thick clouds; or the region of the air, from whence the rain descends to water the hills, as in Ps 104:13.

who maketh the clouds his chariot; to ride in; in these sometimes Jehovah rides to execute judgment on his enemies, Isaiah 19:1 and in these sometimes he appears in a way of grace and mercy to his people,

Exodus 13:21, in these, as in chariots, Christ went up to heaven; and in these will he come a second time; and into these will the saints be caught up to meet the Lord in the air at his coming, Acts 1:9.

who walketh upon the wings of the wind; see Psalms 18:10 which is expressive of his swiftness in coming to help and assist his people in time of need; who helps, and that right early; and may very well be applied both to the first and second coming of Christ, who came leaping upon the mountains, and skipping upon the hills, when he first came; and, when he comes a second time, will be as a roe or a young hart upon the mountains of spices, Song of Solomon 2:8. The Targum is,

"upon the swift clouds, like the wings of an eagle;''

hence, perhaps, it is, the Heathens have a notion of Jupiter's being carried in a chariot through the air, when it thunders and lightens {k}.
