Numbers 35:13

¹¹Then ye shall appoint you cities to be cities of refuge for you; that the slayer may flee thither, which killeth any person at unawares.

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

— Numbers 35:13 —

¹⁴Ye shall give three cities on this side Jordan, and three cities shall ye give in the land of Canaan, which shall be cities of refuge.

¹⁵These six cities shall be a refuge, both for the children of Israel, and for the stranger, and for the sojourner among them: that every one that killeth any person unawares may flee thither.
