² Command the Israelites to give, from the inheritance that they possess, towns for the Levites to live in; you shall also give to the Levites pasture lands surrounding the towns. ³ The towns shall be theirs to live in, and their pasture lands shall be for their cattle, for their livestock, and for all their animals. ⁴ The pasture lands of the towns, which you shall give to the Levites, shall reach from the wall of the town outwards a thousand cubits all around.
