1 Chronicles 19:14-19

Joab and the people with him approached the Arameans for battle, and they fled before him. When the Ammonites saw that the Arameans had fled, they likewise fled before Joab’s brother Abishai and entered the city. Then Joab went to Jerusalem. When the Arameans realized that they had been defeated by Israel, they sent messengers to summon the Arameans who were beyond the Euphrates River. They were led by Shophach, the commander of Hadadezer’s army. When this was reported to David, he gathered all Israel and crossed the Jordan. He came up to the Arameans and lined up against them. When David lined up to engage them, they fought against him. But the Arameans fled before Israel, and David killed seven thousand of their charioteers and forty thousand foot soldiers. He also killed Shophach, commander of the army. When Hadadezer’s subjects saw that they had been defeated by Israel, they made peace with David and became his subjects. After this, the Arameans were never willing to help the Ammonites again.
