2 Samuel 18:1-2

1Then David 1numbered the people who were with him and 2set over them commanders of thousands and commanders of hundreds.

2David sent the people out, 3one third under the 4command of Joab, one third under the 5command of Abishai the son of Zeruiah, Joab’s brother, and one third under the 6command of 7Ittai the Gittite. And the king said to the people, “I myself will surely go out with you also.”
