Joshua 20:4-6

BBE(i) 4 And if anyone goes in flight to one of those towns, and comes into the public place of the town, and puts his cause before the responsible men of the town, they will take him into the town and give him a place among them where he may be safe. 5 And if the one who has the right of punishment comes after him, they are not to give the taker of life up to him; because he was the cause of his neighbour's death without designing it and not in hate. 6 And he is to go on living in that town till he has to come before the meeting of the people to be judged; till the death of him who is high priest at that time: then the taker of life may come back to his town and to his house, to the town from which he had gone in flight.
