1 Chronicles 19:7-9

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.
