Daniel 6:6-9

So the administrators and satraps went together to the king and said to him, “May King Darius live forever. All the administrators of the kingdom  — the prefects, satraps, advisers, and governors — have agreed that the king should establish an ordinance and enforce an edict that, for thirty days, anyone who petitions any god or man except you, the king, will be thrown into the lions’ den. Therefore, Your Majesty, establish the edict and sign the document so that, as a law of the Medes and Persians, it is irrevocable and cannot be changed.” So King Darius signed the written edict.
