Ezekiel 48:13-14

“The land allotted to the Levites will be the same size and shape as that belonging to the priests—8-1/3 miles long and 3-1/3 miles wide. Together these portions of land will measure 8-1/3 miles long by 6-2/3 miles wide. None of this special land may ever be sold or traded or used by others, for it belongs to the LORD; it is set apart as holy.
