The queen of Sheba heard of King Solomon's fame, and she traveled to Jerusalem to test him with difficult questions. She brought with her a large group of attendants, as well as camels loaded with spices, jewels, and a large amount of gold. When she and Solomon met, she asked him all the questions that she could think of. 1
