Ezekiel 45:1

“Moreover, when you divide the land by lot for inheritance, you shall [set apart and] offer an allotment (contribution) to the LORD, a holy portion of the land [to be used for sacred purposes]. The length shall be 25,000 cubits, and the width shall be 20,000 cubits. It shall be holy (set apart for sacred use) within its every area. [Ezek 48:9, 12, 13]
