The ophanim or ofanim (Heb. "wheels" אוֹפַנִּים ’ōphannīm; singular: אוֹפָן ’ōphān, ofan), also called galgalim (galgallim, גַּלְגַּלִּים - "spheres", "wheels", "whirlwinds"; singular: galgal, גַּלְגַּל), refer to the wheels seen in Ezekiel's vision of the chariot (Hebrew merkabah) in Ezekiel 1:15-21. One of the Dead Sea scrolls (4Q405) construes them as angels; late sections of the Book of Enoch (61:10, 71:7) portray them as a class of celestial beings who (along with the Cherubim and Seraphim) never sleep, but guard the throne of God.
These "wheels" have been associated[by whom?] with Daniel 7:9 (mentioned as galgal, traditionally "the wheels of galgallin", in "fiery flame" and "burning fire") of the four, eye-covered wheels (each composed of two nested wheels), that move next to the winged Cherubim, beneath the throne of God. The four wheels move with the Cherubim because the spirit of the Cherubim is in them. The late Second Book of Enoch (20:1, 21:1) also referred to them as the "many-eyed ones".
The 'thrones'; also known as 'ophanim' (offanim) and 'galgallin', are creatures that function as the actual chariots of God driven by the cherubs. They are characterized by peace and submission; God rests upon them. Thrones are depicted as great wheels containing many eyes, and reside in the area of the cosmos where material form begins to take shape. They chant glorias to God and remain forever in his presence. They mete out divine justice and maintain the cosmic harmony of all universal laws.
