'Chief' in the Bible

If the chief priest by doing wrong becomes a cause of sin to the people, then let him give to the Lord for the sin which he has done, an ox, without any mark, for a sin-offering.

And the chief priest is to take some of its blood and take it to the Tent of meeting;

But he shall not defile himself, being a chief man among his people, to profane himself.

And he who is the chief priest among his brothers, on whose head the holy oil has been put, who is marked out to put on the holy robes, may not let his hair go loose or have his clothing out of order as a sign of sorrow.
