"Now when the boy went down to wash his feet in the river, a large fish suddenly leaped out of the water and tried to swallow his foot. He shouted in alarm.
But the angel said to him, "Take hold of the fish and don't let it get away!" The boy seized the fish and hauled it up on the shore.
The angel then told him: "Cut the fish open and take out its gall, heart, and liver, and keep them with you; but throw away the entrails. Its gall, heart, and liver make useful medicines."
After the lad had cut the fish open, he put aside the gall, heart, and liver. Then he broiled and ate part of the fish; the rest he salted and kept for the journey.
Afterward they traveled on together till they were near Media. The boy asked the angel this question: "Brother Azariah, what medicinal value is there in the fish's heart, liver, and gall?"
He answered: "As regards the fish's heart and liver, if you burn them so that the smoke surrounds a man or a woman who is afflicted by a demon or evil spirit, the affliction will leave him completely, and no demons will ever return to him again.
And as for the gall, if you rub it on the eyes of a man who has cataracts, blowing into his eyes right on the cataracts, his sight will be restored."
-Tobit 6:3-9 (New American Bible)
Just for the record, this “Angel” actually IS teaching witchcraft. Note that the cure is universal ... a “miracle” available to anyone that correctly performs the ritual with the correct ingredients. Not that neither prayer to God nor praise for what God has done is suggested by any part of this. It is a “ritual” (spell) able to control demons without the intervention of God or the need for one anointed by God. It is a ”ritual” (spell) to cause or cure a physical condition without the need for God’s blessing. That is witchcraft and the teaching of false spirits.
Compare this with the ashes of the Red Heifer and the actions for leprosy in Deuteronomy and Leviticus.
