104:1b-4 The writer pictured God creating the heavens. Splendor and majesty clothe God in the sense that they manifest Him as clothing makes a statement about the person who wears it. Light is good because it brings life and blessing. When God created light He communicated part of His nature to His creation (Gen. 1:3-5). God created the sky as a tent above man's head. The writer pictured God building a loft for Himself beyond the water above, namely the clouds. Riding on the clouds and wind symbolize God's majestic authority (cf. 68:4). Verse 4 is a poetic description of the angels (cf. Heb. 1:7). Angels do His bidding as wind and fire carry out the will of God on earth.
104:5-9 The psalmist described God creating the earth and then covering it with a blanket as one would cover a new-born infant. He pictured the earth as though it was a building and stressed the stability of what God had made. He did not mean that the earth has literal foundations and is flat. God proceeded to separate the waters on the earth from those above the earth (vv. 6b-7; cf. Gen. 1:6-8). Then he separated the dry ground from the waters on the earth (vv. 8-9; cf. Gen. 1:9-13). The seas are humanly unmanageable, but God set their boundaries and prohibited the waters from crossing them. The frequent references to God controlling water in this psalm demonstrate His sovereignty over all that is difficult to manage in creation.
104:10-18 God also caused springs to erupt in valleys so the animal world could find water and drink. In other words, God provided graciously for His creatures' needs. The song of the birds appears to be a song of praise to God for His provision (v. 12b). God causes the vegetable world to produce for the benefit of His creatures as well. Clearly man's ability to grow food depends on God's more basic provisions. Wine makes people feel good, olive oil makes them look good, and food enables them to produce good things of all kinds. All of God's provisions are for our welfare. He desires to bless humankind. He even provides for the welfare of trees, birds, and insignificant animals. God has indeed made the earth a remarkable habitat for humanity.
"Baal was supposedly the source of life's staples, bread (Ugar. lhm), wine (yn), and oil (smn). In direct contradiction to this, the psalmists asserted that the Lord softens the earth with showers (65:10) and brings forth food [Heb. lehem] from the earth; wine [yayin] that gladdens the heart of man, oil [semen] to make his face shine, and bread [lehem] that sustains his heart' (104:14-15)."169
104:19-23 God's creation of daytime and nighttime were also provisions for God's creatures, especially mankind (cf. Gen. 1:14-17).
