2 Samuel 18:1-2

New Century Version

18 David counted his men and placed over them commanders of thousands and commanders of hundreds. ² He sent the troops out in three groups. Joab commanded one-third of the men. Joab’s brother Abishai son of Zeruiah commanded another third. And Ittai from Gath commanded the last third. King David said to them, “I will also go with you.”
