WNT(i)
3 For judges and magistrates are to be feared not by right-doers but by wrong-doers. You desire--do you not? --to have no reason to fear your ruler. Well, do the thing that is right, and then he will commend you.
4 For he is God's servant for your benefit. But if you do what is wrong, be afraid. He does not wear the sword to no purpose: he is God's servant--an administrator to inflict punishment upon evil-doers.
