Joshua 20 deals with sanctuary cities for those who have unintentionally kills someone. However, I'm trying to get a better understanding of what Joshua 20:6 is stating.
NASB Joshua 20:4-6
4 He shall flee to one of these cities, and shall stand at the entrance of the gate of the city and state his case in the hearing of the elders of that city; and they shall [d]take him into the city to them and give him a place, so that he may dwell among them. 5 Now if the avenger of blood pursues him, then they shall not deliver the manslayer into his hand, because he struck his neighbor without premeditation and did not hate him beforehand. 6 He shall dwell in that city until he stands before the congregation for judgment, until the death of the one who is high priest in those days. Then the manslayer shall [e]return to his own city and to his own house, to the city from which he fled.’”
A) Is Joshua 20:6 stating that the following 2 conditions have to be met in order for the guilty manslayer to return to his own home town?
until he stands before the congregation for judgment
until the death of the one who is high priest in those days
B) Also, I can understand that the manslayer needs to dwell in the sanctuary city until the congregation judges him, but I do Not understand why he would be free to return to his home town when the high priest at that particular point in time dies. Why is that?
