then Toi sent Joram his son unto king David, to salute him, and to bless him—because he had fought against Hadadezer and smitten him; for Hadadezer had wars with Toi—and he brought with him vessels of silver, and vessels of gold, and vessels of brass.

for... had been Tou’s opponent in war He was his antagonist, and this is proven above (v. 3): “And David smote Hadarezer” (note Rashi’s reading). Now what connection do they have to Hamath to wage war there? But [the matter is that] Hadarezer, the king of Zobah, went to wage war against Tou the king of Hamath in Hamath, during which David came upon him and smote him. and all vessels of gold, of silver, and of copper he brought to David; and so it appears in II Samuel (8: 10): “... and in his possession were vessels of silver, and vessels of gold, and vessels of copper.”
Rashi
ברכתי means MY PRESENT — a present such as this that is brought, when one has an audience with a person after an interval of time is intended only as a greeting. Now wherever the term "blessing” (ברכה) is used in connection with an audience — as for example, (47:7) “Jacob blessed (ויברך) Pharaoh”, and (2 Kings 18:31) "make your peace (ברכה) with me” mentioned in connection with Sennacherib, and also (2 Samuel 8:10) to salute him and to bless him (לברכו)” mentioned in connection with Toi, King of Hamath — they all signify greeting, O.I. saluer. So that here, too: ברכתי really means “mon salut” — my greetings and the term is then transferred to the greeting-present.
