1 And I saw in those days how long cords were given to those angels, and they took to themselves wings and flew, and they went towards the north. 2 And I asked the angel, saying unto him: 'Why have those (angels) taken these cords and gone off?' And he said unto me: 'They have gone to measure.' 3 And the angel who went with me said unto me: 'These shall bring the measures of the righteous, And the ropes of the righteous to the righteous, That they may stay themselves on the name of the Lord of Spirits for ever and ever. 4 The elect shall begin to dwell with the elect, And those are the measures which shall be given to faith And which shall strengthen righteousness.

15 The angel who spoke to me had a golden measuring rod with which to measure the city and its foundation stones and wall. 16 Now the city is laid out as a square, its length and width the same. He measured the city with the measuring rod at 1,400 miles (its length and width and height are equal). 17 He also measured its wall, 144 cubits according to human measurement, which is also the angel’s.
