Ezekiel 28:12
12 “Son of man, sing a lament for the king of Tyre, and say to him, ‘This is what the Sovereign Lord says: “‘You were the sealer of perfection, full of wisdom, and perfect in beauty. 13 You were in Eden, the garden of God. Every precious stone was your covering, the ruby, topaz, and emerald, the chrysolite, onyx, and jasper, the sapphire, turquoise, and beryl; your settings and mounts were made of gold. On the day you were created they were prepared. 14 I placed you there with an anointed guardian cherub; you were on the holy mountain of God; you walked about amidst fiery stones. 15 You were blameless in your behavior from the day you were created, until sin was discovered in you.
1 Enoch 24:2
1 And from there I went to another place on the earth, and he showed me a mountain range of fire that burned day and night. 2 I went beyond it and saw seven magnificent mountains, each distinct from the others, with stones that were magnificent and beautiful, overall glorious in appearance and fair exterior: three towards the east, stacked one on top of the other, and three towards the south, each one upon the other, with deep rough ravines, none of which connected with any other. 3 The seventh mountain was in the midst of these, and it was the tallest, resembling the seat of a throne, with fragrant trees encircling the throne.
Notes and References
"... These fiery mountains (see verse 1), which are spectacular, glimmering gemstones, are drawn from ancient Near Eastern conceptions of the abode of the God/the gods and His/their council. On the bejeweled cosmic mountain abode of the gods/God, see comments and footnoted sources at 18:7. This is the point of the language of Ezekiel 28:11–14. When the prophet describes the anointed cherub as “walking among the stones of fire,” his point is that the cherub was in the divine abode, the place of the divine council ..."
