According to the author of 1 Kings, King Solomon received gifts and treasures from traders, spice merchants, and leaders from different countries. This shows how rich and respected he was because everyone wanted to give him nice things.
1 Kings 10:15: Beside [that he had] of the merchantmen, and of the traffick of the spice merchants, and of all the kings of Arabia, and of the governors of the country. [governors: or, captains]
Mentions a similar account but varies in details, leading to discrepancies in descriptions found in 1 Kings 10:15.
2 Chronicles 9:14: Beside [that which] chapmen and merchants brought. And all the kings of Arabia and governors of the country brought gold and silver to Solomon. [governors: or, captains]
