Tobit's guide, Azariah, was his angel Raphael in disguise.

Tuesday, 10/2/18

Although we are trained to pray to our Guardian Angels, they do not reveal themselves to us.

We see an exception to that in the Book of Tobit where Tobit's guardian angel,  Azariah, reveals himself to actually be the angel Raphael; Raphael, one of seven who 0000000serve before God'000s throne.
