Daniel 6:5

Then said these men, in conferring with one another concerning ways and means of removing the hated rival, We shall not find any occasion against this Daniel except we find it against him concerning the Law of his God, regarding the practice of his religion. This is the course which is often followed by the enemies of the believers: if they cannot discredit the Christians in any matter pertaining to their duties, they try to show that the observance of their religious worship is dangerous to the state.
