Solomon’s reputation for wisdom spread throughout the known world:
1 Kings 10:10 When the queen of Sheba heard of Solomon’s fame, which brought honor to the name of the Lord, she came to test him with hard questions.
She wasn’t the only one:
1 Kings 10:23-25 So King Solomon became richer and wiser than any other king on earth. People from every nation came to consult him and to hear the wisdom God had given him. Year after year everyone who visited brought him gifts of silver and gold, clothing, weapons, spices, horses, and mules.
