Daniel 6:10-12

But when Daniel learned that the law had been signed, he went home and knelt down as usual in his upstairs room, with its windows open toward Jerusalem. He prayed three times a day, just as he had always done, giving thanks to his God. Then the officials went together to Daniel’s house and found him praying and asking for God’s help. So they went straight to the king and reminded him about his law. “Did you not sign a law that for the next thirty days any person who prays to anyone, divine or human—except to you, Your Majesty—will be thrown into the den of lions?” “Yes,” the king replied, “that decision stands; it is an official law of the Medes and Persians that cannot be revoked.”
