1 Chronicles 19:7-15

7They had 32,000 chariots to use in the battle. They also received help from the king of Maakah and his army. All these men made their camp near Medeba. At the same time King Hanun had brought together the Ammonite soldiers from their towns. They were all ready to fight.

8David heard news about this. So he sent Joab with all the soldiers in his army to fight against them.

9The Ammonite soldiers marched out from their city. They stood at the entrance of their city and they were ready to fight. The other kings and their soldiers stayed in the fields near the city.

10Joab saw that there were two groups of the enemy's soldiers. They were ready to attack his army from different sides. So he chose some of Israel's best soldiers. Joab himself led them to attack the Syrian soldiers in the fields.

11He told his brother Abishai to lead the rest of Israel's army to fight against the Ammonites.

12Joab said to Abishai, ‘If the Syrian soldiers are too strong for me, you must come to rescue me. But if the Ammonites are too strong for you, I will come to rescue you.

13Be strong! We must be brave as we fight on behalf of our people and the cities of our God. The Lord will do what he decides is good.’

14Then Joab and his group of soldiers went to fight against the Syrians. As they marched towards the Syrian soldiers, they ran away.

15The Ammonites saw that the Syrians were running away from Joab. So they also ran away from his brother Abishai's men. They went back into their city. So Joab returned to Jerusalem.
