Yechezkel 42:7-9

Orthodox Jewish Bible

⁷ And the wall that was outside over against the leshakhot, toward the khatzer hakhitzonah on the forepart of the leshakhot, the length thereof was fifty cubits.

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.
