'High Priest' in the Bible

The community is to release the inadvertent killer from the blood avenger and return him to the town of refuge where he had fled. He is to live there until the High Priest dies, who will have anointed him with holy oil.

The inadvertent killer is to live in the town of refuge until the High Priest dies. After the death of the High Priest, the inadvertent killer is to return to the land of his inheritance.

You are not to receive payment of a ransom for someone who had fled to a town of refuge but then left to live in his homeland before the death of the high priest.
