Daniel 6:14-15

6:14 When the king heard this, he was very upset and began thinking about how he might rescue Daniel. Until late afternoon he was struggling to find a way to rescue him. 6:15 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.”
