When the news came to Joab—for Joab had supported Adonijah although he had not supported Absalom—Joab fled to the tent of the Lord and caught hold of the horns of the altar.
Now Absalom had set Amasa over the army instead of Joab. Amasa was the son of a man named Ithra the Ishmaelite, who had married Abigal the daughter of Nahash, sister of Zeruiah, Joab's mother.
And David sent forth the army, one third under the command of Joab, one third under the command of Abishai the son of Zeruiah, Joab's brother, and one third under the command of Ittai the Gittite. And the king said to the men, “I myself will also go out with you.”
