I remember this girl friend of mine that was not a JW told me the bible says that you are not to swear, so I had her show me were it says that, but I do not think that scripture is talking about that kind of swearing. I think it means to not take an oath.
I think I should remember that if I ever have to take the witness stand, when they ask you to put your hand on the bible and say I swear to tell the truth the whole truth and nothing but the truth, and I will tell the judge the bible says for me to not to do that. I bet that would go over well The judge would probably get me for contempt of court
I know I am very careful about making promises...
