Ezekiel 42:8-10

King James Version

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.

¹⁰ The chambers were in the thickness of the wall of the court toward the east, over against the separate place, and over against the building.
