Ezekiel 45:2-4

Within this area there was to be a space 500 cubits by 500 cubits (about 833 feet by 833 feet). This was the size of the temple complex (cf. Ezekiel 42:20). Surrounding this complex there would be an open space of an additional 50 cubits (83 feet), a kind of green belt. This sacred space would facilitate and illustrate the holiness of the sanctuary area. The temple sanctuary would stand within this 25,000 by 10,000 cubits (8.3 miles by 3.3 miles) area and constitute the most holy part of the land. The Zadokite priests would live in the land outside the open space around the temple complex within this larger area (cf. Ezekiel 48:10-12).
