Daniel 6:13-15 English Revised Version (ERV)

13. Then answered they and said before the king, That Daniel, which is of the children of the captivity of Judah, regardeth not thee, O king, nor the interdict that thou hast signed, but maketh his petition three times a day.

14. Then the king, when he heard these words, was sore displeased, and set his heart on Daniel to deliver him: and he laboured till the going down of the sun to rescue him.

15. Then these men assembled together unto the king, and said unto the king, Know, O king, that it is a law of the Medes and Persians, that no interdict nor statute which the king establisheth may be changed.
