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.

Bede
AD 735
The Lord gutted the fish when he exposed more extensively to his saints the devil’s wickedness and tore from their flesh, as it were, the secrets of his snares. He put away his heart for himself because he wanted to point out in the holy books his cunning, of which it is written, “Now the serpent was more cunning than any of the beasts of the earth”; and of this heart Paul too says, “For we are well aware of his intentions.” He also put away the gall, since, in his concern for caution he wanted the extent of the malicious fury with which he raged against the human race to be written about and put on record. The liver too he put away because he deigned to make known to us through the teachers of the truth the mischievous maturity of his intrigues against us. For they say that it is by the heat and power of the liver the hidden properties of the food that is eaten are “cooked out” and reach the system. But when with careful consideration we seek to find in what order the things we propose to do are to be carried out, we, as it were, cook out by the heat of the liver the foods received in the stomach.
