2 Samuel 10:15-17

But when the Syrians saw that they had been defeated by Israel, they gathered themselves together. And Hadadezer sent and brought out the Syrians who were beyond the Euphrates. They came to Helam, with Shobach the commander of the army of Hadadezer at their head. And when it was told David, he gathered all Israel together and crossed the Jordan and came to Helam. The Syrians arrayed themselves against David and fought with him.
