1 Enoch 71:5
3 The archangel Michael took me by my right hand, lifted me up, and led me through all the secrets, showing me all the secrets of righteousness. 4 He revealed to me all the secrets of the ends of heaven, and all the chambers of the stars and luminaries, from where they emerge before the holy ones. 5 My spirit was taken into the highest heaven where I saw a structure built of crystals with tongues of living fire between them. 6 I observed the girdle of fire encircling this fiery house, with streams of living fire on all four sides.
Revelation 21:10
10 So he took me away in the Spirit to a huge, majestic mountain and showed me the holy city, Jerusalem, descending out of heaven from God. 11 The city possesses the glory of God; its brilliance is like a precious jewel, like a stone of crystal-clear jasper. 12 It has a massive, high wall with twelve gates, with twelve angels at the gates, and the names of the twelve tribes of the nation of Israel are written on the gates. 13 There are three gates on the east side, three gates on the north side, three gates on the south side, and three gates on the west side. 14 The wall of the city has twelve foundations, and on them are the twelve names of the twelve apostles of the Lamb. 15 The angel who spoke to me had a golden measuring rod with which to measure the city and its foundation stones and wall.
Notes and References
"... There are many references to God's heavenly throne in texts such as 1 Enoch 60:2, 62:3, and 84:2, as well as the Apocalypse of Abraham 18:12, but not all include a temple or city. In 1 Enoch 14:14-23, Enoch is swept up into heaven and beholds a vast white house encircled by fire. Inside, he finds another house of fire with a throne at its center, flanked by cherubim and the Glorious One seated upon it, signifying the heavenly temple. Enoch witnesses this once more in 1 Enoch 71:5-11. The heavenly throne doesn't always conjure an image of a heavenly temple, but it might encompass acts of service, prayer, and worship. This portrayal of the heavenly temple and city offers a solution to the problem of human defilement of the city by envisioning the city as fundamentally heavenly, isolated from earthly human contact. Additionally, the universal importance of Jerusalem is highlighted by emphasizing its significance and uniqueness in this world. Jerusalem is posited at "the middle of the earth," as suggested by the Sibylline Oracles 5:250, and echoed in 1 Enoch 26:1, 2 Enoch 72:35, and Jubilees 8:12, 19, a notion occasionally found in the Old Testament, such as in Ezekiel 38:12 and Judges 9:37. Jerusalem is distinctively God's city, as declared in 4 Ezra 10:7, where Ezra states, "From all the cities that have been built you have consecrated Zion for yourself." Additionally, 1 Enoch 25:3 portrays it as the earthly location of God's throne ..."
