Matthew Henry on 2 Samuel 8:9-14
Here is, 1. The court made to David by the king of Hamath, who, it seems was at this time at war with the king of Zobah. He hearing of David's success against his enemy, sent his own son ambassador to him (Sa2 8:9, Sa2 8:10), to congratulate him on his victory, to return him thanks for the favour he had done him in breaking the power of one he was in fear of, and to beg his friendship.

The valley of salt - Supposed to be a large plain abounding in this mineral, about a league from the city of Palmyra or Tadmor in the wilderness.
John Gill on 2 Samuel 8:13
And David gat him a name,.... Fame and reputation in the several nations of the world for valour and courage, for the many and signal victories that he obtained; the Jewish writers generally refer this to his humanity in burying the dead bodies of his enemies slain in war, which gained him great esteem among all, and even his very enemies; but nothing of that kind is pointed at here, but his conquests: or "he made himself a name"; erected a triumphal arch (b) in memory of his victories:
when he returned from smiting of the Syrians in the valley of salt,
being eighteen thousand men; in the relation of this fact in different places some difficulties arise, both as to the people smitten, and…
