1 Enoch

And from thence I went to another place of the earth, and he showed me a mountain range of fire which burnt day and night.

¹ Καὶ ἔδειξέν μοι ὄρη πυρὸς καιόμενα νυκτός.

And I went beyond it and saw seven magnificent mountains all differing each from the other, and the stones (thereof) were magnificent and beautiful, magnificent as a whole, of glorious appearance and fair exterior: three towards the east, one founded on the other, and three towards the south, one upon the other, and deep rough ravines, no one of which joined with any other.
