Daniel 6:8-10

Now, Your Majesty, issue the decree and put it in writing so that it cannot be altered—in accordance with the law of the Medes and Persians, which cannot be repealed.” So King Darius put the decree in writing. 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.
