'Ordinance' in the Bible

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 30 days, anyone who petitions any god or man except you, the king, will be thrown into the lions’ den.

Then these men went to the king and said to him, “You as king know it is a law of the Medes and Persians that no edict or ordinance the king establishes can be changed.”
