'Chief Priest' in the Bible

son of Abishua, son of Phinehas, son of Eleazar, son of Aaron the chief priest--

Guard and look after [them] until you weigh [them] before the chief priests, the Levites, and the heads of the {families} of Israel in Jerusalem, in the chamber of the house of Yahweh."

Then Ezra stood up and made the chief priests, Levites, and all of Israel swear to do according to what was said. So they swore this oath.
