Numbers 35:9-11

New Revised Standard Version, Anglicised Catholic Edition

Cities of Refuge

⁹ The Lord spoke to Moses, saying: ¹⁰ Speak to the Israelites, and say to them: When you cross the Jordan into the land of Canaan, ¹¹ then you shall select cities to be cities of refuge for you, so that a slayer who kills a person without intent may flee there.
