1 Chronicles 27:34

Jehoiada the son of Benaiah, and Abiathar succeeded Ahithophel; and Joab was the commander of the king’s army.

He had conferred with Joab the son of Zeruiah and with Abiathar the priest; and following Adonijah they helped him.

Now David had said, “Whoever strikes down a Jebusite first shall be chief and commander.” Joab the son of Zeruiah went up first, so he became chief.

The third commander of the army for the third month was Benaiah, the son of Jehoiada the priest, as chief; and in his division were 24,000.
