and he said unto me, To measure Jerusalem; not literally understood, which was not yet thoroughly built; but the Gospel church, often so called; see Hebrews 12:22 and this measuring of it denotes the conformity of it to the rule of God's word; a profession of the true doctrines of it, and an observance of the ordinances of it, as delivered in it; and an agreement of the walk, life, and conversation of its members with it:
to see what [is] the breadth thereof, and what [is] the length thereof; the length of the New Jerusalem is as large as the breadth; its length, breadth, and height, are equal, Revelation 21:16.
