Numbers 35:6-7

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.
