Then David dispatched the people, one-third under the command of Joab, one-third under the command of Abishai the son of Zeruiah and brother of Joab, and one-third under the command of Ittai the Gittite. Then David said to the people, “I myself will go out with you.”
Say to Amasa, ‘Are you not my bone and my flesh? May God do to me, and more so, if you are not commander of the army before me from now on in the place of Joab.’ ”
And Joab the son of Zeruiah, with the servants of David, went out in order to meet together at the pool of Gibeon. They sat down, one group on one side of the pool and the other group on the side of the pool opposite them.
Then they called to the king, and Eliakim the son of Hilkiah, who was over the household, Shebna the scribe, and Joah the son of Asaph, the recorder, came out to them.
Then Eliakim son of Hilkiah, who was over the household, Shebna the scribe, and Joah the son of Asaph, the recorder, came to Hezekiah with their clothes torn and told him the words of the Rabshakeh.
David had said, “Whoever strikes Jebus first will be the commander and leader of the army.” And Joab the son of Zeruiah went up first, and became the commander.
