When the news reached Joab (for Joab had supported Adonijah, although he had not supported Absalom), he ran to the tent of the Lord and grabbed hold of the horns of the altar.
Absalom had made Amasa general in command of the army in place of Joab. (Now Amasa was the son of an Israelite man named Jether, who had married Abigail the daughter of Nahash and sister of Zeruiah, Joab’s mother.)
David then sent out the army – a third under the leadership of Joab, a third under the leadership of Joab’s brother Abishai son of Zeruiah, and a third under the leadership of Ittai the Gittite. The king said to the troops, “I too will indeed march out with you.”
I will get revenge and pay them back at the time their foot slips; for the day of their disaster is near, and the impending judgment is rushing upon them!”
