Daniel 6:10-12

And when Daniel knew that the writing was signed, he went into his house (now his windows were open in his chamber toward Jerusalem); and he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime. Then these men assembled together, and found Daniel making petition and supplication before his God. Then they came near, and spake before the king concerning the king’s interdict: Hast thou not signed an interdict, that every man that shall make petition unto any god or man within thirty days, save unto 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.
