112 The word “prisoner” is not in the Greek text but is implied.
113 Pilate then offered to release Jesus, reminding the Jewish authorities that they had a custom that he release one prisoner for them at the Passover. There is no extra-biblical evidence alluding to the practice. It is, however, mentioned in Matthew and Mark, described either as a practice of Pilate (Mark 15:6) or of the Roman governor (Matt 27:15). These references may explain the lack of extra-biblical attestation: The custom to which Pilate refers here (18:39) is not a permanent one acknowledged by all the Roman governors, but one peculiar to Pilate as a means of appeasement, meant to better relations with his subjects. Such a limited meaning is certainly possible and consistent with the statement here.
