Revelation 21:17-19

Young's Literal Translation

¹⁷ and he measured its wall, an hundred forty-four cubits, the measure of a man, that is, of the messenger;

¹⁸ and the building of its wall was jasper, and the city [is] pure gold -- like to pure glass;

¹⁹ and the foundations of the wall of the city with every precious stone have been adorned; the first foundation jasper; the second, sapphire; the third, chalcedony; the fourth, emerald;
