'Wall' in the Bible

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,

and the wall of the city had twelve foundations, and in them names of the twelve apostles of the Lamb.

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

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

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

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;
