12 Also, my fellow believers, I want to say something important about how you talk. If you say that you will do something, do not say, "If I do not do it, may God in heaven [MTY] punish me." Do not even say, "If I do not do it, may someone here on earth [MTY] punish me." Do not say anything like that. Instead, if you say "Yes," then do what you said that you would do. If you say "No," then do not do it. Otherwise, God will condemn you.
