Ezekiel 48:9-10

9The allotment that you shall set apart to the Lord shall be twenty-five thousand cubits in length and ten thousand in width.

10The holy allotment shall be for these, namely for the 1priests, toward the north twenty-five thousand cubits in length, toward the west ten thousand in width, toward the east ten thousand in width, and toward the south twenty-five thousand in length; and the sanctuary of the Lord shall be in its midst.
