'High priest' in the Bible

and the assembly shall rescue the manslayer out of the hand of the avenger of blood, and the assembly shall restore him to the city of his refuge, whither he had fled; and he shall abide in it until the death of the high-priest, who was anointed with the holy oil.

for the manslayer should have remained in the city of his refuge until the death of the high-priest; but after the death of the high-priest he may return into the land of his possession.

And he shall dwell in that city, until he have stood before the assembly in judgment, until the death of the high-priest that shall be in those days; then shall the slayer return, and come unto his own city, and unto his own house, unto the city from whence he fled.
