Daniel 6:10, 12

Now when Daniel learned that the decree had been published, he went home to his upstairs room where the windows opened toward Jerusalem. Three times a day he got down on his knees and prayed, giving thanks to his God, just as he had done before.

So they went to the king and spoke to him about his royal decree: “Did you not publish a decree that during the next thirty days anyone who prays to any god or human being except to you, Your Majesty, would be thrown into the lions’ den?” The king answered, “The decree stands—in accordance with the law of the Medes and Persians, which cannot be repealed.”
