'Cities of Refuge' in the Bible

And the cities which ye shall give unto the Levites, they shall be the six cities of refuge, which ye shall give for the manslayer to flee unto: and besides them ye shall give forty and two cities.

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

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

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.
