Revelation 21:17-20

Living Bible

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.
