Ezekiel 40:13-15

13The man also measured between the back wall of one room and the back wall of the room opposite. It was 12½ metres from one wall to the other wall, across the passage.

14The entrance room had pillars on the outside that were 30 metres high. The yard was all around three sides of the room.

15The passage was 25 metres long, from the gate at the front to the entrance room into the yard.
