Solomon sent to Hiram - Made an interchange of ambassadors and friendly greetings. Josephus tells us that the correspondence between Hiram and Solomon was preserved in the archives of the Tyrians even in his time. But this, like many other assertions of the same author, is worthy of little credit.

And Solomon sent to Hiram,.... A letter, either by the hand of his ambassadors when they returned, as Kimchi thinks, or by ambassadors Solomon sent on purpose. Josephus (w) appeals to the Tyrian archives for the genuineness of these letters that passed between Hiram and Solomon; and Eupolemus, an Heathen writer (x) has both this which Solomon sent to Hiram, and that which Hiram sent in answer to it, which agree with those in the sacred records:
saying: as follows.
