2 Samuel 10:19

19. They made peace The kings or chieftains under Hadarezer made peace. It seems that Hadarezer himself was not present at this war, so that in this treaty with Israel his officers acted for him.

The Syrians feared to help… Ammon any more They had now suffered two disastrous defeats in attempting to help the Ammonites, the first in the field before Medeba, (2 Samuel 10:8; comp. 1 Chronicles 19:0,) and the second at Helam. But, as we have argued in the notes on 2 Samuel 10:6, and 2 Samuel 8:3, there was yet another engagement subsequent to these, but probably intimately connected with them, and not long after. Hadarezer went to recover his border along the Euphrates, and this act was too much like violation of the peace David had just made with his subject-kings, and hence the war with Hadarezer, the interference of the Syrians of Damascus, and the consequent subjection of all Syria to the kingdom of Israel, recorded in chapter 8.
