1 Kings 10:1-5

When the queen of Sheba heard about the fame of Solomon and his relationship to the LORD, she came to test Solomon with hard questions. Arriving at Jerusalem with a very great caravan—with camels carrying spices, large quantities of gold, and precious stones—she came to Solomon and talked with him about all that she had on her mind. Solomon answered all her questions; nothing was too hard for the king to explain to her. When the queen of Sheba saw all the wisdom of Solomon and the palace he had built, the food on his table, the seating of his officials, the attending servants in their robes, his cupbearers, and the burnt offerings he made at the temple of the LORD, she was overwhelmed.
