Daniel 6:12-13

6:12 So they approached the king and said to him, “Did you not issue an edict to the effect that for the next thirty days anyone who prays to any god or human other than to you, O king, would be thrown into a den of lions?” The king replied, “That is correct, according to the law of the Medes and Persians, which cannot be changed.” 6:13 Then they said to the king, “Daniel, who is one of the captives from Judah, pays no attention to you, O king, or to the edict that you issued. Three times daily he offers his prayer.”
