Numbers 35:13-15

New Revised Standard Version, Anglicised

¹³ The cities that you designate shall be six cities of refuge for you: ¹⁴ you shall designate three cities beyond the Jordan, and three cities in the land of Canaan, to be cities of refuge. ¹⁵ These six cities shall serve as refuge for the Israelites, for the resident or transient alien among them, so that anyone who kills a person without intent may flee there.
