Revelation 21
12 Ref having also a wall great and high, having twelve gates, and at the gates twelve messengers, and names written thereon, which are `those' of the twelve tribes of the sons of Israel,
13 Ref at the east three gates, at the north three gates, at the south three gates, at the west three gates;
14 Ref and the wall of the city had twelve foundations, and in them names of the twelve apostles of the Lamb.
15 Ref And he who is speaking with me had a golden reed, that he may measure the city, and its gates, and its wall;
16 Ref 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 Ref and he measured its wall, an hundred forty-four cubits, the measure of a man, that is, of the messenger;
18 Ref and the building of its wall was jasper, and the city `is' pure gold -- like to pure glass;
19 Ref 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;
