Daniel 6:12 NLT

[12] So they went straight to the king and reminded him about his law. "Did you not sign a law that for the next thirty days any person who prays to anyone, divine or human-except to you, Your Majesty-will be thrown into the den of lions?" "Yes," the king replied, "that decision stands; it is an official law of the Medes and Persians that cannot be revoked."
