1 Kings 10:1-3

1And the queen of Sheba heard of the fame of Solomon in connection with the name of Jehovah, and came to prove him with enigmas.

2And she came to Jerusalem with a very great train, with camels that bore spices and gold in very great abundance, and precious stones; and she came to Solomon, and spoke to him of all that was in her heart.

3And Solomon explained to her all she spoke of: there was not a thing hidden from the king that he did not explain to her.
