'Trial' in the Bible

The killer will stay in that city until he stands before the congregation for the trial, until the death of the one who is the high priest in those days. Then {the killer will return} to his city and to his house, to the city from which he fled.'"

These were the cities designated for all the {Israelites}, and for the foreigners dwelling among them, for anyone that kills a person unintentionally to flee there, and not die by the hand of the avenger of blood, {until there is a trial} before the congregation.
