Numbers 35:1-3

And Jehovah speaketh unto Moses, in the plains of Moab, by Jordan, near Jericho, saying,

`Command the sons of Israel, and they have given to the Levites of the inheritance of their possession cities to inhabit; also a suburb for the cities round about them ye do give to the Levites.

And the cities have been to them to inhabit, and their suburbs are for their cattle, and for their goods, and for all their beasts.
