1 Enoch 71:5

1 And it came to pass after this that my spirit was translated And it ascended into the heavens: And I saw the holy sons of God. They were stepping on flames of fire: Their garments were white [and their raiment], And their faces shone like snow. 2 And I saw two streams of fire, And the light of that fire shone like hyacinth, And I fell on my face before the Lord of Spirits. 3 And the angel Michael [one of the archangels] seized me by my right hand, And lifted me up and led me forth into all the secrets, And he showed me all the secrets of righteousness. 4 And he showed me all the secrets of the ends of the heaven, And all the chambers of all the stars, and all the luminaries, Whence they proceed before the face of the holy ones. 5 And he translated my spirit into the heaven of heavens, And I saw there as it were a structure built of crystals, And between those crystals tongues of living fire. 6 And my spirit saw the girdle which girt that house of fire, And on its four sides were streams full of living fire, And they girt that house.

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.
