Daniel 6:10-15

Now when Daniel knew that the document was signed, he entered his house (now in his roof chamber he had windows open toward Jerusalem); and he continued kneeling on his knees three times a day, praying and giving thanks before his God, as he had been doing previously. Then these men came by agreement and found Daniel making petition and supplication before his God. Then they approached and spoke before the king about the king’s injunction, “Did you not sign an injunction that any man who makes a petition to any god or man besides you, O king, for thirty days, is to be cast into the lions’ den?” The king replied, “The statement is true, according to the law of the Medes and Persians, which may not be revoked.” Then they answered and spoke before the king, “Daniel, who is one of the exiles from Judah, pays no attention to you, O king, or to the injunction which you signed, but keeps making his petition three times a day.” Then, as soon as the king heard this statement, he was deeply distressed and set his mind on delivering Daniel; and even until sunset he kept exerting himself to rescue him. Then these men came by agreement to the king and said to the king, “Recognize, O king, that it is a law of the Medes and Persians that no injunction or statute which the king establishes may be changed.”
