Ezekiel 48:20

Having particularly measured out ten thousand for the priests, and ten thousand for the Levites, and five thousand for the city broadways, these make in all twenty-five thousand; and the length of each the same, twenty-five thousand; here is evidently a perfect equilateral square, whose sides are twenty-five thousand each. With the possession of the city; the land assigned for the city, being added to that of the priests and Levites, makes their twice ten thousand to amount to twenty-five thousand broad.
