Tobit 6:5
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?
