'Chief Priest' in the Bible

'And the company have delivered the man-slayer out of the hand of the redeemer of blood, and the company have caused him to turn back unto the city of his refuge, whither he hath fled, and he hath dwelt in it till the death of the chief priest, who hath been anointed with the holy oil.

for in the city of his refuge he doth dwell till the death of the chief priest; and after the death of the chief priest doth the man-slayer turn back unto the city of his possession.
