The Apocalypse of Abraham 19
2I said: "Here am I!"
3And He said: "Consider the expanses which are under the firmament on which thou art (now) placed, and see how on no single expanse is there any other but He whom thou hast sought, or who hath loved thee."
4And while He was yet speaking (and) lo! the expanses opened, and beneath me the heavens.
6And I looked from the mountain in which I stood [downwards] to the sixth firmament, and saw there a multitude of angels, of (pure) spirit, without bodies, who carried out the commands of the fiery angels who were upon the eighth firmament, as I was standing suspended over them.
7And behold, upon this firmament there were no other powers of (any) other form, but only angels of (pure) spirit, like the power which I saw on the seventh firmament.
8And He commanded that the sixth firmament should be taken away.
