Numbers 35:9-11

Darby Translation

⁹ And Jehovah spoke to Moses, saying,

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 for yourselves cities: cities of refuge shall they be for you; that a manslayer may flee thither, who without intent smiteth a person mortally.
