Tobit 6:7–9
7 Then the young man questioned the angel and said to him, “Brother Azariah, what medicinal value is there in the fish’s heart and liver, and in the gall?” 8 He replied, “As for the fish’s heart and liver, you must burn them to make a smoke in the presence of a man or woman afflicted by a demon or evil spirit, and every affliction will flee away and never remain with that person any longer. 9 And as for the gall, anoint a person’s eyes where white films have appeared on them; blow upon them, upon the white films, and the eyess will be healed.”
