In 1993, Dieter Lührmann published a reconstruction of the more intelligible side of P.Oxy. 4009. He demonstrated that this side, which he called the recto, consists of passages parallel to Matt 10.16 par., Luke 10.3 and 2 Clem. 5.2–4. He also argued that the passage stems from the Gospel of Peter. However, Lührmann considered it impossible (‘ausgeschlossen’) to reconstruct the other side of the fragment. The aim of the present article is to demonstrate that a full reconstruction of this less intelligible side of P.Oxy. 4009, lines 1–13, is possible and that it enriches our knowledge of the Gospel of Peter with a new pericope which is an interesting parallel of Luke 7.36–50. The reconstruction also demonstrates that the side reconstructed by Lührmann is actually the verso, and that both sides together point towards the well-known anti-Jewish redactional tendencies of the author of the Gospel of Peter.
