Should we apply Deuteronomy 19:15—21 which describes the necessity of more than one witness to other circumstances? According to Matthew 18:15—18 we should. The idea of finding as many witnesses as possible for any circumstance is how we verify many things and that should include verifying scripture as well. When our Creator tells us the same thing more than two or three times, we should consider that fact and truth, no matter who might disagree with it.
