Ezekiel 41:10

Between the chambers that on one side joined to the temple, and were public repositories for offerings, and tithes, &c., and those other chambers, which were built on the wall of this inner court, and were lodgings for the priests, there was a void space, or pavement, in the open air, twenty cubits broad, and these round about on all sides of the court, and probably some rails, or balusters, or low wall round too before them enclosing this space.
