Yechezkel 42:8-10

Orthodox Jewish Bible

⁸ For the length of the leshakhot that were in the khatzer hakhitzonah was fifty cubits; and, hineh, before the Heikhal were a hundred cubits.

⁹ And from below these leshakhot was the entrance on the east side, as one goeth into them from the khatzer hakhitzonah.

¹⁰ In the thickness of the wall of the khatzer toward the east, facing the Gizrah, and over against the Binyan, were leshakhot (side rooms).
