Daniel 6:7-9
7
All the presidents of the kingdom, the deputies and the satraps, the counselors and the governors, have consulted together to establish a royal statute, and to make a strong decree, that whoever shall ask a petition of any god or man for thirty days, except of you, O king, he shall be cast into the den of lions.
8
Now, O king, establish the decree, and sign the writing, that it not be changed, according to the law of the Medes and Persians, which doesn't alter.
9
Therefore king Darius signed the writing and the decree.
