The Book of Daniel, Chapter 6 - Part 2

The king realizes he has been tricked. He knows he has just been judicially outmaneuvered. He realizes that he will be personally responsible for the death of Daniel if he doesn't figure a way out.

Daniel 6:13 NKJV So they answered and said before the king, "That Daniel, who is one of the captives from Judah, does not show due regard for you, O king, or for the decree that you have signed, but makes his petition three times a day."

Daniel 6:15 NKJV Then these men approached the king and said to the king, "Know, O king, that it is the law of the Medes and Persians that no decree or statute which the king establishes may be changed."
