Psalms 18:10

10. He rode upon a cherub The plural is cherubim, and the word commonly occurs in this form. The name is given to those beings which are supposed to symbolize the direct agencies employed to execute the divine will, and who thus stand as the immediate representatives of God, (Genesis 3:24,) answering to the τεσσαρα ζωα ( four living creatures) of the apocalypse, (Revelation 4:6, et al.,) and unfortunately translated beasts in our English Bible. The same are the כרובים ( cherubim) of Ezekiel 10:0, and the four חיות ( living creatures) of Ezekiel 1:0. The cherubim seem to represent the beneficent and avenging attributes of God.

See note on Psalms 80:1. In 1 Chronicles 28:18, compare “chariot of the cherubim” with Psalms 68:17.

Yea, he did fly Literally, he flew swiftly. The verb denotes the rapid flight of birds of prey, as in Deuteronomy 28:49; Jeremiah 48:10. Ainsworth supposes it means the glancing of those swift-winged birds which fly with a swing, as when they swoop for their prey.
