Then they came near, and spake before the king concerning the king's decree; Hast thou not signed a decree, that every man that shall ask a petition of any God or man within thirty days, save of thee, O king, shall be cast into the den of lions? The king answered and said, The thing is true, according to the law of the Medes and Persians, which altereth not. Shall be cast into the den of lions - Either this was the royal menagerie, like that place in the Tower of London, where wild beasts are kept for the king's pleasure, and the public amusement; or they were kept for the purpose of devouring certain criminals, which the laws might consign to that kind of death. This is most likely, from the case before us.
