Numbers 35:12 ASV

¹⁰  Speak unto the children of Israel, and say unto them, When ye pass over the Jordan into the land of Canaan,

¹¹  then ye shall appoint you cities to be cities of refuge for you, that the manslayer that killeth any person unwittingly may flee thither.

¹²  And the cities shall be unto you for refuge from the avenger, that the manslayer die not, until he stand before the congregation for judgment.

¹³  And the cities which ye shall give shall be for you six cities of refuge.

¹⁴  Ye shall give three cities beyond the Jordan, and three cities shall ye give in the land of Canaan; they shall be cities of refuge.
