Numbers 35:7-8

All the cities which yee shall giue to the Leuites, shalbe eight and fourtie cities: them shall ye giue with their suburbes.

And concerning the cities which yee shall giue, of the possession of the children of Israel: of many ye shall take more, and of few ye shall take lesse: euery one shall giue of his cities vnto the Leuites, according to his inheritance, which hee inheriteth.
