'Doubts' in the Bible

because an excellent spirit, and knowledge, and understanding, interpreting of dreams, and showing of dark sentences, and dissolving of doubts, were found in the same Daniel, whom the king named Belteshazzar. Now let Daniel be called, and he will show the interpretation.

But I have heard of you, that you can give interpretations, and dissolve doubts; now if you can read the writing, and make known to me its interpretation, you shall be clothed with purple, and have a chain of gold about your neck, and shall be the third ruler in the kingdom.
