Tobit 6:5–8

5 So the young man did as the angel told him; and they roasted and ate the fish.

And they both continued on their way until they came near to Ecbatana. 6 Then the young man said to the angel, “Brother Azarias, of what use is the liver and heart and gall of the fish?” 7 He replied, “As for the heart and liver, if a demon or evil spirit gives trouble to any one, you make a smoke from these before the man or woman, and that person will never be troubled again. 8 And as for the gall, anoint with it a man who has white films in his eyes, and he will be cured.”
