Daniel 6:8-9

8All the supervisors of the realm, the magistrates and satraps, ministers and governors, have all agreed that the king should issue an edict and enforce a decree that anyone who prays to any god or man for 30 days other than you O king, will be cast into the lions’ den.

9Now, O king, issue the decree and put it in writing so that it may not be altered, according to the law of the Medes and Persians, which cannot be repealed.”
