2 Samuel 10 New King James Version (NKJV)
The Ammonites and Syrians Defeated
10 It happened after this that the king of the people of Ammon died, and Hanun his son reigned in his place. 2 Then David said, “I will show kindness to Hanun the son of Nahash, as his father showed kindness to me.”
So David sent by the hand of his servants to comfort him concerning his father. And David’s servants came into the land of the people of Ammon. 3 And the princes of the people of Ammon said to Hanun their lord, “Do you think that David really honors your father because he has sent comforters to you? Has David not rather sent his servants to you to search the city, to spy it out, and to overthrow it?”
4 Therefore Hanun took David’s servants, shaved off half of their beards, cut off their garments in the middle, at their buttocks, and sent them away. 5 When they told David, he sent to meet them, because the men were greatly [a]ashamed. And the king said, “Wait at Jericho until your beards have grown, and then return.”
6 When the people of Ammon saw that they had made themselves repulsive to David, the people of Ammon sent and hired the Syrians of Beth Rehob and the Syrians of Zoba, twenty thousand foot soldiers; and from the king of Maacah one thousand men, and from Ish-Tob twelve thousand men. 7 Now when David heard of it, he sent Joab and all the army of the mighty men. 8 Then the people of Ammon came out and put themselves in battle array at the entrance of the gate. And the Syrians of Zoba, Beth Rehob, Ish-Tob, and Maacah were by themselves in the field.
9 When Joab saw that the battle line was against him before and behind, he chose some of Israel’s best and put them in battle array against the Syrians. 10 And the rest of the people he put under the command of Abishai his brother, that he might set them in battle array against the people of Ammon. 11 Then he said, “If the Syrians are too strong for me, then you shall help me; but if the people of Ammon are too strong for you, then I will come and help you. 12 Be of good courage, and let us be strong for our people and for the cities of our God. And may the Lord do what is good in His sight.”
13 So Joab and the people who were with him drew near for the battle against the Syrians, and they fled before him. 14 When the people of Ammon saw that the Syrians were fleeing, they also fled before Abishai, and entered the city. So Joab returned from the people of Ammon and went to Jerusalem.
15 When the Syrians saw that they had been defeated by Israel, they gathered together. 16 Then [b]Hadadezer sent and brought out the Syrians who were beyond [c]the River, and they came to Helam. And [d]Shobach the commander of Hadadezer’s army went before them. 17 When it was told David, he gathered all Israel, crossed over the Jordan, and came to Helam. And the Syrians set themselves in battle array against David and fought with him. 18 Then the Syrians fled before Israel; and David killed seven hundred charioteers and forty thousand horsemen of the Syrians, and struck Shobach the commander of their army, who died there. 19 And when all the kings who were servants to [e]Hadadezer saw that they were defeated by Israel, they made peace with Israel and served them. So the Syrians were afraid to help the people of Ammon anymore.
2 Samuel 10 New International Version (NIV)
David Defeats the Ammonites
10 In the course of time, the king of the Ammonites died, and his son Hanun succeeded him as king. 2 David 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, 3 the 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?” 4 So Hanun seized David’s envoys, shaved off half of each man’s beard, cut off their garments at the buttocks, and sent them away.
5 When 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.”
6 When 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.
7 On hearing this, David sent Joab out with the entire army of fighting men. 8 The 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.
9 Joab 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. 10 He put the rest of the men under the command of Abishai his brother and deployed them against the Ammonites. 11 Joab 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. 12 Be 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.”
13 Then Joab and the troops with him advanced to fight the Arameans, and they fled before him. 14 When 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.
15 After the Arameans saw that they had been routed by Israel, they regrouped. 16 Hadadezer had Arameans brought from beyond the Euphrates River; they went to Helam, with Shobak the commander of Hadadezer’s army leading them.
17 When 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. 18 But 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. 19 When 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.
