Ezekiel 40:17-19

17The man took me through the entrance gate into the outside yard of the temple. I saw 30 rooms there, all along the wall of the yard. A path of flat stones was in front of the rooms.

18The path went all around the yard and it covered the space between the gates. It was called the lower path.

19The man measured across the outside yard. He measured from the lower gate to the higher gate that went into the inside yard. The man measured 50 metres between the two gates.
