"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. [11] Then these men went as a group and found Daniel praying and asking God for help. [12] 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 man except to you, O king, would be thrown into the lions' den?'
"The king answered, 'The decree stands—in accordance with the laws of the Medes and Persians, which cannot be repealed.'
"[13] Then they said to the king, 'Daniel, who is one of the exiles from Judah, pays no attention to you, O king, or to the decree you put in writing. He still prays three times a day.'"
-- Daniel 6:10-13 (NIV)
