Ezekiel 42:1-2

Ezekiel’s guide next took him out the north inner gate into the outer court and showed him another building. It stood between the "separate area," the 20-cubit (33 feet 4 inches) space that bordered the temple proper, and "the building toward the north," evidently the complex of rooms in the outer court that stood against the north wall of the temple complex. The length of this building, east to west, was 100 cubits (166 feet 8 inches), and its width, north to south, was 50 cubits (83 feet 4 inches). This structure had a door on its north side.
