Ezekiel 42:6-8

New Catholic Bible

⁶ For they were divided into three stories and they had no pillars as the courts had. Thus, the upper chambers were more narrow than those on the lower and middle levels.

⁷ There was an outer wall parallel to the chambers that extended out toward the outer court; it was fifty cubits long. ⁸ The chambers facing the outer court were fifty cubits long, while those facing the temple were one hundred cubits long.
