Tobit 6:6-8

New Revised Standard Version, Anglicised Catholic Edition

⁶ So after cutting open the fish the young man gathered together the gall, heart, and liver; then he roasted and ate some of the fish, and kept some to be salted.

The two continued on their way together until they were near Media.^{[a] 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.
