When you swear too, tell the truth on Oath or just swear to something, for somebody, that's just saying it's ok to swear, and now is negating (taking away from) the truth, for now is a fact and is a plain lie. Any type of swearing, is a permission to lie, truth is self evident, truth does not need to be sworn in or on anything. To swear is to swear, just as to be is to be, to say is to say. Just as the truth is self evident, so is swearing.
Truth: + plus+positive word.
Swearing: _minus_negative word, would become a fact, and grow into a lie.
