2 Samuel 10:16, 17
Hadadezer sent messengers to bring more Arameans from beyond the Euphrates, and they came to Helam with Shobach the commander of Hadadezer’s army leading them. / When this was reported to David, he gathered all Israel, crossed the Jordan, and went to Helam. Then the Arameans arrayed themselves against David and fought against him.
