After the first repulse of the Ammonites and their Syrian allies by Joab, Hadarezer sent his army to the assistance of his kindred the people of Maachah, Rehob and Ishtob. 1 Chronicles 19:16; 2 Samuel 10:15. Compare 2 Samuel 10:8.

Under the command of Shophach or Shobach, the captain of the host, they crossed the Euphrates, joined the other Syrians, and encamped at a place called Helam. David himself came from Jerusalem to take the command of the Israelite army. As on the former occasion, the route was complete.
