2 Samuel 10:15-17

And when the Syrians saw that they were smitten before Israel, they gathered themselves together. And Hadarezer sent, and brought out the Syrians that were beyond the river: and they came to Helam; and Shobach the captain of the host of Hadarezer went before them. And when it was told David, he gathered all Israel together, and passed over Jordan, and came to Helam. And the Syrians set themselves in array against David, and fought with him.
