Tobit 6:1-6

1 And as they went on their journey, they came in the evening to the river Tigris, and they lodged there.
2 And when the young man went down to wash himself, a fish leaped out of the river, and would have devoured him.
3 Then the angel said unto him, Take the fish. And the young man laid hold of the fish, and drew it to land.
4 To whom the angel said, Open the fish, and take the heart and the liver and the gall, and put them up safely.
5 So the young man did as the angel commanded him; and when they had roasted the fish, they did eat it: then they both went on their way, till they drew near to Ecbatane.
6 Then the young man said to the angel, Brother Azarias, to what use is the heart and the liver and the gal of the fish?
