Book of Tobit
Tobit goes blind and feels hopeless, but recovers his sight through the advice of an Angel called Raphael. Also mentioned is Tobit's son called Tobias, who is traveling eastward to collect money, accompanied by the Angel, Raphael, who tells Tobit of a woman named Sarah who is looking to get married. Her earlier marriages were not completed because shortly beforehand the man would always die mysteriously, which saddens Sarah. This time, though, the man does not die and in the end Tobias and Sarah are happily married. The story of Tobit is important for its teaching about guardian angels and for the need to always remain loyal to God during difficult times.
