So King Darius issued the written interdict.

Now let the king issue a written interdict so that it cannot be altered, according to the law of the Medes and Persians, which cannot be changed.

So they approached the king and said to him, “Did you not issue an edict to the effect that for the next thirty days anyone who prays to any god or human other than to you, O king, would be thrown into a den of lions?” The king replied, “That is correct, according to the law of the Medes and Persians, which cannot be changed.”

Then they said to the king, “Daniel, who is one of the captives from Judah, pays no attention to you, O king, or to the edict that you issued. Three times daily he offers his prayer.”

Then those men came by collusion to the king and said to him, “Recall, O king, that it is a law of the Medes and Persians that no edict or decree that the king issues can be changed.”

To all the supervisors of the kingdom, the prefects, satraps, counselors, and governors it seemed like a good idea for a royal edict to be issued and an interdict to be enforced. For the next thirty days anyone who prays to any god or human other than you, O king, should be thrown into a den of lions.
