2 Samuel 10:7-14

7When David heard about this, he sent Joab and all his warriors to fight them.

8The Ammonite troops came out and drew up their battle lines at the entrance of the city gate, while the Arameans from Zobah and Rehob and the men from Tob and Maacah positioned themselves to fight in the open fields.

9When Joab saw that he would have to fight on both the front and the rear, he chose some of Israel’s elite troops and placed them under his personal command to fight the Arameans in the fields.

10He left the rest of the army under the command of his brother Abishai, who was to attack the Ammonites.

11“If the Arameans are too strong for me, then come over and help me,” Joab told his brother. “And if the Ammonites are too strong for you, I will come and help you.

12Be courageous! Let us fight bravely for our people and the cities of our God. May the Lord’s will be done.”

13When Joab and his troops attacked, the Arameans began to run away.

14And when the Ammonites saw the Arameans running, they ran from Abishai and retreated into the city. After the battle was over, Joab returned to Jerusalem.
