Daniel 6:6-8

Then these commissioners and satraps came by agreement to the king and spoke to him as follows: “King Darius, live forever! All the commissioners of the kingdom, the prefects and the satraps, the high officials and the governors have consulted together that the king should establish a statute and enforce an injunction that anyone who makes a petition to any god or man besides you, O king, for thirty days, shall be cast into the lions’ den. Now, O king, establish the injunction and sign the document so that it may not be changed, according to the law of the Medes and Persians, which may not be revoked.”
