Daniel 6:5

Then said these men
To one another: we shall not find any occasion against this Daniel;
whom they speak of with great disdain and contempt, calling him this Daniel, this fellow, though in the highest post in the kingdom: except we find it against him concerning the law of his God;
about his religion; not that they thought he would be prevailed upon to break the law of his God in any respect; but they knew he was tenacious of the Jewish religion, and of all the laws, rites, and ceremonies of it; if therefore they could get an act passed, and signed by the king, which would any ways affect his religion, or any branch of it, or prohibit the performance of it for any time, they hoped to get an advantage of him, knowing that he would not on any consideration forsake or neglect that; which being said by his enemies was greatly to his honour.
