Ezekiel 48:8-9

“And beside the border of Judah, from the east side to the west side, shall be the allotment and contribution of land which you shall set apart and offer, 25,000 cubits in width, and in length like one of the [tribal] portions, from the east side to the west side; and the sanctuary shall be in the midst of it. The allotment [of land] that you shall set apart and offer to the LORD shall be 25,000 cubits in length and 10,000 in width.
