Numbers 35
2 Ref Give orders to the children of Israel to give to the Levites, from the heritage which is theirs, towns for themselves, with land on the outskirts of the towns.
3 Ref These towns are to be their living-places, with land round them for their cattle and their food and all their beasts,
4 Stretching from the wall of the towns a distance of a thousand cubits all round.
5 The measure of this space of land is to be two thousand cubits outside the town on the east, and two thousand cubits on the south and on the west and on the north, the town being in the middle. This space will be the outskirts of their towns.
