1 Chronicles 19:14-15
14-15But when Joab and his soldiers moved in to fight the Arameans, they ran off in full retreat. Then the Ammonites, seeing the Arameans run for dear life, took to their heels and ran from Abishai into the city.
So Joab withdrew from the Ammonites and returned to Jerusalem.
16When the Arameans saw how badly they'd been beaten by Israel, they picked up the pieces and regrouped; they sent for the Arameans who were across the river; Shophach, commander of Hadadezer's army, led them.
