'Doubts' in the Bible

forasmuch as 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 thee, that thou canst give interpretations, and dissolve doubts; now if thou canst read the writing, and make known to me the interpretation thereof, thou shalt be clothed with purple, and have a chain of gold about thy neck, and shalt be the third ruler in the kingdom.
