Revelation 21:17 YLT

¹⁵  And he who is speaking with me had a golden reed, that he may measure the city, and its gates, and its wall;

¹⁶  and the city lieth square, and the length of it is as great as the breadth; and he did measure the city with the reed -- furlongs twelve thousand; the length, and the breadth, and the height, of it are equal;

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;
