Daniel 6:8-10

8Now let the king issue a written interdict so that it cannot be altered, according to the law of the Medes and Persians, which cannot be changed.

9So King Darius issued the written interdict.

10When Daniel realized that a written decree had been issued, he entered his home, where the windows in his upper room opened toward Jerusalem. Three times daily he was kneeling and offering prayers and thanks to his God just as he had been accustomed to do previously.
