Ezekiel 45:3-5

New Catholic Bible

³ Out of this area you must also set aside a section twenty-five thousand cubits long and ten thousand cubits wide, within which will be the sanctuary, the Holy of Holies. ⁴ This will be the sacred portion of the land belonging to the priests who minister in the sanctuary and approach the Lord to serve him. It will be both a place for their houses as well as a holy place for the sanctuary.

⁵ Another section, twenty-five thousand cubits long and ten thousand cubits wide, will be set apart for the Levites who minister at the temple, so that they will have towns in which to live.
