2 Samuel 18:1-2

Darby Translation

18 And David marshalled the people that were with him, and set captains of thousands and captains of hundreds over them.

² And David sent forth the people, a third part under the hand of Joab, and a third part under the hand of Abishai the son of Zeruiah, Joab's brother, and a third part under the hand of Ittai the Gittite. And the king said to the people, I will surely go forth with you myself also.
