2 Chronicles 9:1

And when the queen of Sheba heard of the fame of Solomon, since the caravans from Canaan penetrated into the most remote corners of Arabia and spread the accounts of his great wisdom everywhere, she came to prove Solomon with hard questions, with epigrammatic riddles and conundrums, such as were much used in the Orient, at Jerusalem, with a very great company, and camels that bare spices, and gold in abundance, and precious stones, with all the pomp and splendor so dear to the heart of the Oriental monarch; and when she was come to Solomon, she communed with him of all that was in her heart, all the difficult questions which she had prepared beforehand.
