Revelation 21:16-20

Living Bible

¹⁶ When he measured it, he found it was a square as wide as it was long; in fact it was in the form of a cube, for its height was exactly the same as its other dimensions—1,500 miles each way. ¹⁷ Then he measured the thickness of the walls and found them to be 216 feet across (the angel called out these measurements to me, using standard units).^[a]

^18-20 The city itself was pure, transparent gold like glass! The wall was made of jasper, and was built on twelve layers of foundation stones inlaid with gems: the first layer^[b] with jasper; the second with sapphire; the third with chalcedony; the fourth with emerald; the fifth with sardonyx; the sixth layer with sardus; the seventh with chrysolite; the eighth with beryl; the ninth with topaz; the tenth with chrysoprase; the eleventh with jacinth; the twelfth with amethyst.
