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.
