Daniel 6:12-15

12So 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.”

13Then they told the king, “That man Daniel, one of the captives from Judah, is ignoring you and your law. He still prays to his God three times a day.”

14Hearing this, the king was deeply troubled, and he tried to think of a way to save Daniel. He spent the rest of the day looking for a way to get Daniel out of this predicament.

15In the evening the men went together to the king and said, “Your Majesty, you know that according to the law of the Medes and the Persians, no law that the king signs can be changed.”
