Joshua 20:3-5

New International Version - UK

³ so that anyone who kills a person accidentally and unintentionally may flee there and find protection from the avenger of blood. ⁴ When they flee to one of these cities, they are to stand in the entrance of the city gate and state their case before the elders of that city. Then the elders are to admit the fugitive into their city and provide a place to live among them. ⁵ If the avenger of blood comes in pursuit, the elders must not surrender the fugitive, because the fugitive killed their neighbour unintentionally and without malice aforethought.
