Ezekiel 42:15-20

15Now when he had made an end of measuring the inner house, he brought me forth toward the gate whose prospect is toward the east, and measured it round about. 16He measured the east side with the measuring reed, five hundred reeds, with the measuring reed round about.1 17He measured the north side, five hundred reeds, with the measuring reed round about. 18He measured the south side, five hundred reeds, with the measuring reed.

19He turned about to the west side, and measured five hundred reeds with the measuring reed. 20He measured it by the four sides: it had a wall round about, five hundred reeds long, and five hundred broad, to make a separation between the sanctuary and the profane place.
