Throughout Revelation, several references to the Temple are made . This Temple appears to be of heavenly origin. When the eschaton arrives in , the reader expects the temple to come down from heaven with the New Jerusalem. Revelation 21 even contains typical New Jerusalem terminology that accompanies a restored Temple. Specific measurements are given for the new city (Ezekiel 40–48, 4Q554), and the city is built with gold, sapphires, and emeralds (Isaiah, Tobit). In addition, 21:21 references the "twelve gates." Revelation maintains another typical aspect of New Jerusalem tradition – the reunification of the twelve tribes of Israel (Ezekiel 48:33-34, 4Q554).
