Daniel 6:12

So they went to the king and talked to him about the law he had made. They said, “Didn’t you sign a law that says no one may pray to any god or human except you, O king? Doesn’t it say that anyone who disobeys during the next thirty days will be thrown into the lions’ den?” The king answered, “Yes, that is the law, and the laws of the Medes and Persians cannot be canceled.”
