Ezekiel 42:7-9

King James Version

⁷ And the wall that was without over against the chambers, toward the utter court on the forepart of the chambers, the length thereof was fifty cubits.

⁸ For the length of the chambers that were in the utter court was fifty cubits: and, lo, before the temple were an hundred cubits.

⁹ And from under these chambers was the entry on the east side, as one goeth into them from the utter court.
