Revelation 21:15-17

Darby Translation

¹⁵ And he that spoke with me had a golden reed [as] a measure, that he might measure the city, and its gates, and its wall.

¹⁶ And the city lies four-square, and its length [is] as much as the breadth. And he measured the city with the reed—twelve thousand stadia: the length and the breadth and height of it are equal.

¹⁷ And he measured its wall, a hundred [and] forty-four cubits, [a] man's measure, that is, [the] angel's.
