9 The Ammonites came out and prepared for battle at the city gate. The kings who had come to help were out in the field by themselves.
10 Joab saw that there were enemies both in front of him and behind him. So he chose some of the best soldiers of Israel and sent them out to fight the Arameans.
11 Joab put the rest of the army under the command of Abishai, his brother. Then they went out to fight the Ammonites.
12 Joab said to Abishai, “If the Arameans are too strong for me, you must help me. Or, if the Ammonites are too strong for you, I will help you.
13 Be strong. We must fight bravely for our people and the cities of our God. The Lord will do what he thinks is right.”
14 Then Joab and the army with him went to attack the Arameans, and the Arameans ran away.
15 When the Ammonites saw that the Arameans were running away, they also ran away from Joab’s brother Abishai and went back to their city. So Joab went back to Jerusalem.
