2 Samuel 10:1-19 NIV
David Defeats the Ammonites
1In the course of time, the king of the Ammonites died, and his son Hanun succeeded him as king. 2David thought, “I will show kindness to Hanun son of Nahash, just as his father showed kindness to me.” So David sent a delegation to express his sympathy to Hanun concerning his father.
When David’s men came to the land of the Ammonites, 3the Ammonite commanders said to Hanun their lord, “Do you think David is honoring your father by sending envoys to you to express sympathy? Hasn’t David sent them to you only to explore the city and spy it out and overthrow it?” 4So Hanun seized David’s envoys, shaved off half of each man’s beard,
cut off their garments at the buttocks, and sent them away.
5When David was told about this, he sent messengers to meet the men, for they were greatly humiliated. The king said, “Stay at Jericho till your beards have grown, and then come back.”
6When the Ammonites realized that they had become obnoxious to David, they hired twenty thousand Aramean foot soldiers from Beth Rehob and Zobah, as well as the king of Maakah with a thousand men, and also twelve thousand men from Tob.
7On hearing this, David sent Joab out with the entire army of fighting men. 8The Ammonites came out and drew up in battle formation at the entrance of their city gate, while the Arameans of Zobah and Rehob and the men of Tob and Maakah were by themselves in the open country.
9Joab saw that there were battle lines in front of him and behind him; so he selected some of the best troops in Israel and deployed them against the Arameans. 10He put the rest of the men under the command of Abishai his brother and deployed them against the Ammonites. 11Joab said, “If the Arameans are too strong for me, then you are to come to my rescue; but if the Ammonites are too strong for you, then I will come to rescue you. 12Be strong, and let us fight bravely for our people and the cities of our GOD. The LORD Will Do what is good in HIS Sight.”
13Then Joab and the troops with him advanced to fight the Arameans, and they fled before him. 14When the Ammonites realized that the Arameans were fleeing, they fled before Abishai and went inside the city. So Joab returned from fighting the Ammonites and came to Jerusalem.
15After the Arameans saw that they had been routed by Israel, they regrouped. 16Hadadezer had Arameans brought from beyond the Euphrates River;
they went to Helam, with Shobak the commander of Hadadezer’s army leading them.
17When David was told of this, he gathered all Israel, crossed the Jordan and went to Helam. The Arameans formed their battle lines to meet David and fought against him.
18But they fled before Israel, and David killed seven hundred of their charioteers and forty thousand of their foot soldiers.a He also struck down Shobak the commander of their army, and he died there. 19When all the kings who were vassals of Hadadezer saw that they had been routed by Israel, they made peace with the Israelites and became subject to them.
So the Arameans were afraid to help the Ammonites anymore.
David’s Kindness Ridiculed By the Ammonites
Nahash had been an enemy to Israel, yet had showed kindness to David. David therefore resolves gratefully to return it. We do not know exactly the nature or extent of the obligation which David was under to the king of the Ammonites; but it is likely that the Nahash here mentioned was the same who had attacked Jabesh-gilead, and whom Saul defeated: as David had taken refuge with the Moabites.
From there David went to Mizpah in Moab and said to the king of Moab, "Would you let my father and mother come and stay with you until I learn What GOD Will Do for me?"
And this was contiguous to the king of the Ammonites, his hatred to Saul might induce him to show particular kindness to David.
