'Chief' in the Bible

So David commanded his young men, and they killed them and cut off their hands and feet and hung them beside the pool in Hebron. But they took Ish-bosheth’s head and buried it in Hebron in the tomb of Abner [his relative].

Zadok the son of Ahitub and Ahimelech the son of Abiathar were the [chief] priests, and Seraiah was the scribe;

Benaiah the son of Jehoiada was [head] over both the Cherethites and Pelethites [the king’s bodyguards]; and David’s sons were chief [confidential] advisers (officials) [to the king].

also Ira the Jairite was a priest to David.

These are the names of the mighty men (warriors) whom David had: Josheb-basshebeth, a Tahchemonite, chief of the captains, also called Adino the Eznite (spear) because of the eight hundred men killed [by him] at one time.

Then three of the thirty chief men went down and came to David at harvest time in the cave of Adullam, while an army of Philistines was encamped in the Valley of Rephaim.

Now Abishai the brother of Joab the son of Zeruiah was chief of the thirty. He wielded his spear against three hundred men and killed them, and gained a reputation beside the three.
