2 Chronicles 9:1-2

1When the queen of Sheba heard of the fame of Solomon, she came to Jerusalem to test Solomon with riddles. She was accompanied by a very large number of attendants, with camels bearing spices (balsam oil) and a large amount of gold and precious stones. And when she came to Solomon, she talked with him about all that was on her mind.

2Solomon answered all her questions; nothing was hidden from him which he did not make clear to her.
