2 Chronicles 9:1

1 Now when the queen of Sheba heard of the fame of Solomon, she came to Jerusalem to test Solomon with difficult questions. She had a very large retinue, with camels carrying spices and a large amount of gold and precious stones; and when she came to Solomon, she spoke with him about all that was on her heart.
