Later King Nahash of the Ammonites died and his son succeeded him.

The Ammonites marched out and were deployed for battle at the entrance to the city, while the kings who had come were by themselves in the field.

He put his brother Abishai in charge of the rest of the army and they were deployed against the Ammonites.

When the Ammonites realized that David was disgusted with them, ¹  Hanun and the Ammonites sent 1,000 talents ²  of silver to hire chariots and charioteers from Aram Naharaim, Aram Maacah, and Zobah. ³ 

Joab ¹  said, “If the Arameans start to overpower me, ²  you come to my rescue. If the Ammonites start to overpower you, ³  I will come to your rescue.

When the Ammonites saw the Arameans flee, they fled before Joab’s ¹  brother Abishai and withdrew into the city. Joab went back to Jerusalem. ² 

King David dedicated these things to the Lord, ¹  along with the silver and gold which he had carried off from all the nations, including ²  Edom, ³  Moab, the Ammonites, the Philistines, and Amalek.

David said, “I will express my loyalty ¹  to Hanun son of Nahash, for his father was loyal ²  to me.” So David sent messengers to express his sympathy over his father’s death. ³  When David’s servants entered Ammonite territory to visit Hanun and express the king’s sympathy, ⁴ 

the Ammonite officials said to Hanun, “Do you really think David is trying to honor your father by sending these messengers to express his sympathy? ¹  No, his servants have come to you so they can get information and spy out the land!” ² 

They hired 32,000 chariots, along with the king of Maacah and his army, who came and camped in front of Medeba. The Ammonites also assembled from their cities and marched out to do battle.

When Hadadezer’s subjects saw they were defeated by Israel, they made peace with David and became his subjects. The Arameans were no longer willing to help the Ammonites.

In the spring, at the time when kings normally conduct wars, ¹  Joab led the army into battle and devastated the land of the Ammonites. He went and besieged Rabbah, while David stayed in Jerusalem. Joab defeated Rabbah and tore it down.

He removed the city’s residents and made them do hard labor with saws, iron picks, and axes. ¹  This was his policy ²  with all the Ammonite cities. Then David and all the army returned to Jerusalem.
