Ezekiel 42:15-20

15When the man had finished measuring the inside of the Temple area, he led me out through the east gateway to measure the entire perimeter.

16He measured the east side with his measuring rod, and it was 875 feet long.

17Then he measured the north side, and it was also 875 feet.

18The south side was also 875 feet,

19and the west side was also 875 feet.

20So the area was 875 feet on each side with a wall all around it to separate what was holy from what was common.
