Joshua 20:3-5

Complete Jewish Bible

³ so that anyone who kills someone by mistake and unknowingly may escape there; they will serve as refuges for you from the next-of-kin avenger. ⁴ He is to flee to one of those cities, stand at the entrance to the city gate and state his cause to the city leaders. Then they will bring him into the city with them and give him a place, so that he may live among them. ⁵ If the next-of-kin avenger pursues him, they are not to hand over the killer to him; because he struck his fellow community member unknowingly and had not hated him previously.
