When the news came to Joab, he fled to the Tent of Adonai and grasped the horns of the altar—for Joab had defected to Adonijah, though he had not defected to Absalom.
Now Absalom had set Amasa over the army instead of Joab. (Now Amasa was son of a man whose name was Ithra the Israelite, who had gone to Abigal daughter of Nahash, sister to Zeruiah Joab’s mother.)
Then David sent out the troops, one third under the command of Joab, one third under the command of Joab’s brother Abishai son of Zeruiah, and one third under the command of Ittai the Gittite. The king said to the troops, “I must certainly go out with you also.”
