Ezekiel 48:12-14
48:12 It will be their portion from the allotment of the land, a most holy place, next to the border of the Levites.
48:13 “Alongside the border of the priests, the Levites will have an allotment eight and a quarter miles in length and three and one-third miles in width. The whole length will be eight and a quarter miles and the width three and one-third miles.
48:14 They must not sell or exchange any of it; they must not transfer this choice portion of land, for it is set apart to the Lord.
