Daniel 6:12
King James Version
“Then they came near, and spake before the king concerning the king’s decree; Hast thou not signed a decree, that every man that shall ask of any God or man within thirty days, save of thee, O king, shall be cast into the den of lions? The king answered and said, The thing is true, according to the law of the Medes and Persians, which altereth not.”
Context
9Wherefore king Darius signed the writing and the decree.
10Now when Daniel knew that the writing was signed, he went into his house; and his windows being open in his chamber toward Jerusalem, he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime.
11Then these men assembled, and found Daniel praying and making supplication before his God.
12Then they came near, and spake before the king concerning the king’s decree; Hast thou not signed a decree, that every man that shall ask of any God or man within thirty days, save of thee, O king, shall be cast into the den of lions? The king answered and said, The thing is true, according to the law of the Medes and Persians, which altereth not.
13Then answered they and said before the king, That Daniel, which of the children of the captivity of Judah, regardeth not thee, O king, nor the decree that thou hast signed, but maketh his petition three times a day.

15Then these men assembled unto the king, and said unto the king, Know, O king, that the law of the Medes and Persians That no decree nor statute which the king establisheth may be changed.
