John Gill Commentary 1 Chronicles 18:10

"he sent Hadoram his son to king David, to salute him, and to bless him, because he had fought against Hadarezer and smitten him; (for Hadarezer had wars with Tou;) and [he had with him] all manner of vessels of gold and silver and brass." — 1 Chronicles 18:10 (ASV)
