Ezequiel 28
John Damascene
Ezequiel 28:12-13
One of the angel powers, the marshal of one host, bore in himself no trace of natural evil from his Maker's hand but had been created for good, yet by his own free and deliberate choice he turned aside from good to evil and was stirred up by madness to the desire to take up arms against his Lord God. — BARLAAM AND JOSEPH 7
