Ezekiel 48:8-9

“South of Judah, from the eastern limit to the western limit, is the special portion of holy land that you must set aside. The temple complex will stand in the center. That land will be 25,000 cubits wide and the same length as one of the tribal portions from the east side to the west. The portion that you must set aside for YAHWEH must be 25,000 cubits long and 20,000 cubits wide.
