'Doubts' in the Bible

If the spirit of doubt comes into her husband's heart, and he has doubts of his wife, with good cause; or if he has doubts of her without cause:

Or for a husband who, in a bitter spirit, has doubts in his heart about his wife; let him take her to the priest, who will put in force this law.

Forasmuch as an excellent spirit, and knowledge, and understanding, interpreting of dreams, and shewing of hard sentences, and dissolving of doubts, were found in the same Daniel, whom the king named Belteshazzar: now let Daniel be called, and he will shew the interpretation.

And I have heard of thee, that thou canst make interpretations, and dissolve doubts: now if thou canst read the writing, and make known to me the interpretation thereof, thou shalt be clothed with scarlet, and have a chain of gold about thy neck, and shalt be the third ruler in the kingdom.
