Numbers 35:6-8

King James Version

⁶ And among the cities which ye shall give unto the Levites there shall be six cities for refuge, which ye shall appoint for the manslayer, that he may flee thither: and to them ye shall add forty and two cities.

⁷ So all the cities which ye shall give to the Levites shall be forty and eight cities: them shall ye give with their suburbs.

⁸ And the cities which ye shall give shall be of the possession of the children of Israel: from them that have many ye shall give many; but from them that have few ye shall give few: every one shall give of his cities unto the Levites according to his inheritance which he inheriteth.
