Ezekiel 48:14 (KJV)

And this oblation of the land that is offered shall be unto them a thing most holy by the border of the Levites.

And over against the border of the priests the Levites shall have five and twenty thousand in length, and ten thousand in breadth: all the length shall be five and twenty thousand, and the breadth ten thousand.

And they shall not sell of it, neither exchange, nor alienate the firstfruits of the land: for it is holy unto the Lord.

And the five thousand, that are left in the breadth over against the five and twenty thousand, shall be a profane place for the city, for dwelling, and for suburbs: and the city shall be in the midst thereof.

And these shall be the measures thereof; the north side four thousand and five hundred, and the south side four thousand and five hundred, and on the east side four thousand and five hundred, and the west side four thousand and five hundred.
