2 Chronicles 9:1-4

Now when the queen of Sheba heard about the fame of Solomon, she came to Jerusalem to test Solomon with riddles. She had a very large entourage, with camels carrying balsam oil and a large amount of gold and precious stones; and when she came to Solomon, she spoke with him about everything that was on her heart.

Solomon answered all her questions; nothing was hidden from Solomon which he did not explain to her.

When the queen of Sheba had seen the wisdom of Solomon, the house which he had built,

the food at his table, the seating of his servants, the attendance of his ministers and their attire, his cupbearers and their attire, and his stairway by which he went up to the house of the Lord, she was breathless.
