22:11 cherub. The mighty angelic beings called cherubim (Satan himself was originally the highest of all—Ezekiel 28:14) are always associated with the presence of God as sovereign Creator.
22:11 wind. In the Hebrew, “wind” is the same as “spirit,” so this phrase could refer to “the wings of the Spirit.” In the Bible’s first reference to “the Spirit of God” (Genesis 1:2), He is seen as “moving” in the presence of the primeval waters, with the word the same as that for the fluttering movement of the wings of a great bird. The vibrating motion implies the generating of waves of energy, flowing out from the Spirit to energize the newly created cosmos. Similarly, the divine energy emanates from the Spirit here, but this time in destructive rather than creative power.
22:12 dark waters. The reference to “waters” and “darkness” in these verses seems to fit most naturally with David’s retrospective vision of the ancient judgment of the Flood. The references to “fire” (II Samuel 22:9,13) correlate with the breaking-up of the fountains of the great deep (implying volcanic eruptions) at the time of the Flood, and the reference to “lightning” (II Samuel 22:15) correlates to the sudden rains from heaven.
