1 Chronicles 19:18-19

And the Syrians fled before Israel; and David slew of the Syrians the men of seven thousand chariots, and forty thousand footmen, and killed Shophach the captain of the host. And when the servants of Hadarezer saw that they were put to the worse before Israel, they made peace with David, and served him: neither would the Syrians help the children of Ammon any more.
