When Joab saw that the battle was set against him both in front and in the rear, he chose some of the picked men of Israel and arrayed them against the Arameans;
And David sent forth the army: one third under the command of Joab; one third under the command of Abishai son of Zeruiah, Joab’s brother; and one third under the command of Ittai the Gittite. The king said to the men, “I myself will also go out with you.”
Now Abishai son of Zeruiah, the brother of Joab, was chief of the Thirty. With his spear he fought against three hundred men and killed them and won a name beside the Three.
