Revelation 21:12-21 New English Translation (NET Bible)
12 It has[a] a massive, high wall[b] with twelve gates,[c] with twelve angels at the gates, and the names of the twelve tribes of the nation of Israel[d] are written on the gates.[e] 13 There are[f] 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.[g] 14 The[h] wall of the city has twelve foundations, and on them are the twelve names of the twelve apostles of the Lamb.
15 The angel[i] who spoke to me had a golden measuring rod with which to measure the city and its foundation stones and wall. 16 Now[j] the city is laid out as a square,[k] its length and width the same. He[l] measured the city with the measuring rod[m] at 1,400 miles[n] (its length and width and height are equal). 17 He also measured its wall, 144 cubits[o] according to human measurement, which is also the angel’s.[p] 18 The city’s[q] wall is made[r] of jasper and the city is pure gold, like transparent glass.[s] 19 The foundations of the city’s wall are decorated[t] with every kind of precious stone. The first foundation is jasper, the second sapphire, the third agate,[u] the fourth emerald, 20 the fifth onyx,[v] the sixth carnelian,[w] the seventh chrysolite,[x] the eighth beryl,[y] the ninth topaz, the tenth chrysoprase,[z] the eleventh jacinth,[aa] and the twelfth amethyst. 21 And the twelve gates are twelve pearls—each one of the gates is made from just one pearl! The[ab] main street[ac] of the city is pure gold, like transparent glass.
