1 Enoch 23

¹ From thence I went to another place to the west of the ends of the earth.

² And I saw a burning fire which ran without resting, and paused not from its course day or night but (ran) regularly.

³ And I asked saying: 'What is this which rests not?'

⁴ Then Raguel, one of the holy angels who was with me, answered me and said unto me: 'This course of fire which thou hast seen is the fire in the west which †persecutes† all the luminaries of heaven.'
