Revelation 21:11-15

21:11 The city possesses the glory of God; its brilliance is like a precious jewel, like a stone of crystal-clear jasper. 21:12 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. 21:13 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. 21:14 The wall of the city has twelve foundations, and on them are the twelve names of the twelve apostles of the Lamb.

21:15 The angel who spoke to me had a golden measuring rod with which to measure the city and its foundation stones and wall.
