John 18:15

And Simon Peter followed Jesus, and so did another disciple: that disciple was known unto the high priest, and went in with Jesus into the palace of the high priest.

Ver. 15. That disciple was known to the high priest] Perhaps for that he and his father Zebedee were wont to serve the fat priests with the best and daintiest fish (for this other disciple was John, who had first fled with the rest, and now came sculking in to see what would become of his master). Of the ass-fish Aristotle affirmeth (De Nat. Animal.) that he of all other creatures hath his heart in his belly; such a thing was this priest.
