'Chief' in the Bible

and Benaiah the son of Jehoiada [was over] the Cherethites and the Pelethites; and David's sons were chief ministers.

and also Ira the Jairite was chief minister to David.

These are the names of the mighty men whom David had: Josheb Basshebeth a Tahchemonite, chief of the captains; the same was Adino the Eznite, against eight hundred slain at one time.

Three of the thirty chief men went down, and came to David in the harvest time to the cave of Adullam; and the troop of the Philistines was encamped in the valley of Rephaim.

Abishai, the brother of Joab, the son of Zeruiah, was chief of the three. He lifted up his spear against three hundred and killed them, and had a name among the three.
