Matthew 27:15

27:15 During the feast the governor was accustomed to release one prisoner to the crowd, whomever they wanted.

Mark 15:6

Jesus and Barabbas

15:6 During the feast it was customary to release one prisoner to the people, whomever they requested.

John 18:39

18:39 But it is your custom that I release one prisoner for you at the Passover. So do you want me to release for you the king of the Jews?”

sn The custom of Pilate to release one prisoner is unknown outside the gospels in Jewish writings, but it was a Roman custom at the time and thus probably used in Palestine as well (cf. Matt 27:15; John 18:39).

tn Grk “them”; the referent (the people) has been specified in the translation for clarity.

tn The word “prisoner” is not in the Greek text but is implied.

sn 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.
