Psalms 18:10

And he rode upon a cherub - Compare Isaiah 14:13, note; Isaiah 37:16, note. The cherub in the theology of the Hebrews was a figurative representation of power and majesty, under the image of a being of a high and celestial nature, “whose form is represented as composed from the figures of a man, ox, lion, and eagle,” Ezekiel 1:0; Ezekiel 10:0. Cherubs are first mentioned as guarding the gates of Paradise, Genesis 3:24; then as bearing the throne of God upon their wings through the clouds, Ezekiel 1:0; Ezekiel 10:0; and also as statues or images made of wood and overlaid with gold, over the cover of the ark, in the inner sanctuary of the tabernacle, and of the temple, Exodus 25:18 ff; 1 Kings 6:23-28. Between the two cherubim in the temple, the Shechinah, or visible symbol of the presence of God, rested; and hence, God is represented as “dwelling between the cherubim,” Exodus 25:22; Numbers 7:89; Psalms 80:1; Psalms 99:1. The cherubim are not to be regarded as real existences, or as an order of angels like the seraphim Isaiah 6:2-3, but as an imaginary representation of majesty, as emblematic of the power and glory of God. Here God is represented as “riding on a cherub;” that is, as coming forth on the clouds regarded as a cherub (compare Ezekiel 1:0), as if, seated on his throne, he was borne along in majesty and power amidst the storm and tempest.

And did fly - He seemed to move rapidly on the flying clouds.

Yea, he did fly upon the wings of the wind - Rapidly as the clouds driven along by the wind. The “wings of the wind” are designed to represent the rapidity with which the wind sweeps along. Rapid motion is represented by the flight of birds; hence, the term wings is applied to winds to denote the rapidity of their movement. The whole figure here is designed to represent; the majesty with which God seemed to be borne along on the tempest. Herder renders it, “He flew on the wings of the storm.”
