To him that rideth upon the heavens of heavens, which were of old; lo, he doth send out his voice, and that a mighty voice. Rideth upon the heavens - He who manages the heavens, directing their course and influence, he formed every orb, ascertained its motion, proportioned its solid contents to the orbit in which it was to revolve, and the other bodies which belong to the same system. As an able and skillful rider manages his horse, so does God the sun, moon, planets, and all the hosts of heaven.
He doth send out his voice - At his word of command they run, shed, or reflect their light; and without the smallest deviations obey his will.
Mighty voice - He thunders in the heavens, and men tremble before him.
