And the foundations of the wall of the city were adorned with all manner of precious stones. The first foundation was jasper: the second, sapphire: the third, a chalcedony: the fourth, an emerald: The fifth, sardonyx: the sixth, sard: the seventh, chrysolite: the eighth, beryl: the ninth, a topaz: the tenth, a chrysoprasus: the eleventh, a jacinth: the twelfth, an amethyst."
