Numbers 35:11-14

Leeser(i) 11 Then ye shall appoint unto yourselves proper cities, that they be cities of refuge for you; and thither shall flee the manslayer who killeth any person at unawares. 12 And these cities shall be unto you for a refuge from the avenger; that the manslayer die not, until he have stood before the congregation for trial. 13 And the cities which ye shall give, shall be six cities of refuge unto you; 14 Three of these cities shall ye give on this side of the Jordan, and the three other cities shall ye give in the land of Canaan: cities of refuge shall they be.
