15. And the one who spoke with me was holding a golden measuring rod in order that he could measure the city and its gates and its wall.

17. And he measured its wall, one hundred forty-four cubits according to human measure, which is the angel’s.
18. And the material of its wall is jasper, and the city is pure gold, similar in appearance to pure glass.
