1 Chronicles 19:13-17

Be strong, and let’s show ourselves courageous for the benefit of our people and the cities of our God; and may the Lord do what is good in His sight.”

So Joab and the people who were with him advanced to battle against the Arameans, and they fled from him.

When the sons of Ammon saw that the Arameans had fled, they also fled from his brother Abshai and entered the city. Then Joab came to Jerusalem.

When the Arameans saw that they had been defeated by Israel, they sent messengers and brought out the Arameans who were beyond the Euphrates River, with Shophach the commander of the army of Hadadezer leading them.

When it was reported to 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 formation against the Arameans, they fought against him.
