The angel Bazazeth appears in the grimoire Testament of Solomon
From Testament of Solomon, F. C. Conybeare edition:
And, having glorified God, I asked the dragon-shaped demon, and said: "Tell me, by what angel art thou frustrated?" And he answered: "By the great angel which has its seat in the second heaven, which is called in Hebrew Bazazeth. And I Solomon, having heard this, and having invoked his angel, condemned him to saw up marbles for the building of the Temple of God; and I praised God, and commanded another demon to come before me.
