Midrash sobre Ezequiel 1:27

Four classes of ministering angels minister and utter praise before the Holy One, blessed be He: the first camp (led by) Michael on His right, the second camp (led by) Gabriel on His left, the third camp || (led by) Uriel before Him, and the fourth camp (led by) Raphael behind Him; and the Shekhinah of the Holy One, blessed be He, is in the centre. He is sitting on a throne high and exalted. His throne is high and suspended above in the air. The appearance of His Glory is like the colour of amber. And the adornment of a crown is on His head, and the Ineffable Name is upon His forehead. One half (of His glory) is fire the other half is hail, at His right hand is life and at His left is death. He has a sceptre of fire in His hand and a veil is spread before Him, and His eyes run to and fro throughout the whole earth, and the seven angels, which were created first, minister before Him within the veil, and this (veil) is called Pargod. His footstool is like fire and hail. Fire is flashing continually around His throne, righteousness and judgment are the foundation of His throne. And the likeness of His throne is like a sapphire throne with four legs, and the four holy Chajjôth are fixed to each leg, each one has four faces and each one has four wings, as it is said, "And every one had four faces and four wings" (Ezek. 1:6), and these (Chajjôth) are the Cherubim.
