Ezekiel 48:13-14

13The Levites will also have a special part, south of the part for the priests. It will be the same size. It will measure 12½ kilometres from east to west, and 5 kilometres from north to south. So the land for the priests and for the Levites will be 12½ kilometres from east to west and 10 kilometres from north to south.

14The special part of the land that belongs to the Lord is the best of the whole land. You must not give his land to anyone else or sell it to anyone else. It is holy and it belongs to the Lord.
