Nahash, king of the Ammonites, who had shown kindness to David, dies, and his son Hanun reigns in his place. David sends messengers to console Hanun over his father's death. But the Ammonite princes tell Hanun that David is only sending comforters in order to spy out the land. Hanun takes David's servants, shaves them, cuts their garments in half, up to their hips, and sends them away.
When David is told, he sends to meet them, for the men were greatly ashamed, and tells them to stay at Jericho until their beards have grown. The Ammonites know they have become odious to David and hire chariots and horsemen from Mesopotamia, Aram-maacah and Zobah. Joab goes out with the army and sees that the enemies are in front and behind. He divides his men: he faces the Arameans and leaves his brother Abishai with the rest against the Ammonites.
Joab tells Abishai to be strong for their people and for the cities of their God, and may the Lord do what seems good to him. The Arameans flee, and the Ammonites too. The defeated Arameans gather their forces again, and David crosses the Jordan with all Israel and defeats them. Seven thousand charioteers and forty thousand foot soldiers die, and also Shophach, the commander of the army. Then the servants of Hadadezer make peace with David and serve him, and the Arameans were unwilling to help the Ammonites any more.
