Daniel 6:6-10

Then these high officials and satraps came by agreement to the king and said to him, “O King Darius, live forever! All the high officials of the kingdom, the prefects and the satraps, the counselors and the governors are agreed that the king should establish an ordinance and enforce an injunction, that whoever makes petition to any god or man for thirty days, except to you, O king, shall be cast into the den of lions. Now, O king, establish the injunction and sign the document, so that it cannot be changed, according to the law of the Medes and the Persians, which cannot be revoked.” Therefore King Darius signed the document and injunction. When Daniel knew that the document had been signed, he went to his house where he had windows in his upper chamber open toward Jerusalem. He got down on his knees three times a day and prayed and gave thanks before his God, as he had done previously.
