1 Chronicles 19:14-19

14So Joab and the people who were with him drew near to the battle against the Arameans, and they fled before him. 15When the sons of Ammon saw that the Arameans fled, they also fled before Abshai his brother and entered the city. Then Joab came to Jerusalem.

16When the Arameans saw that they had been 1defeated by Israel, they sent messengers and brought out the Arameans who were beyond the 2River, with Shophach the commander of the army of Hadadezer 3leading them. 17When it was told David, he gathered all Israel together and crossed the Jordan, and came upon them and drew up in formation against them. And when David drew up in battle array against the Arameans, they fought against him. 18The Arameans fled before Israel, and David killed of the Arameans 7,000 charioteers and 40,000 foot soldiers, and put to death Shophach the commander of the army. 19So when the servants of Hadadezer saw that they were 4defeated by Israel, they made peace with David and served him. Thus the Arameans were not willing to help the sons of Ammon anymore.
