These were the cities appointed for all the children of Israel, and for the stranger that sojourneth among them, that whosoever killeth [any] person at unawares might flee thither, and not die by the hand of the avenger of blood, until he stood before the congregation.
Berean Study Bible (BSB) - Joshua 20:9 >These are the cities appointed for all the Israelites and foreigners among them, so that anyone who kills a person unintentionally may flee there and not die by the hand of the avenger of blood prior to standing trial before the assembly.
