Ambrose of Milan, on Num 35:25

“The innocent shall be delivered from the hand of the revenger, and shall be brought back by sentence into the city, to which he had fled, and he shall abide there until the death of the high priest, that is anointed with the holy oil.”

“The man who renounces the vices and rejects the way of life of his countrymen is in flight like Lot. Such a one does not look behind himself but enters that city which is above by the passageway of his thoughts, and he does not withdraw from it until the death of the chief priest who bore the sin of the world. He indeed died once, but he dies for each person who is baptized in Christ's death, that we may be buried together with him and rise with him and walk in the newness of his life.”
