[17:15] 2 tn The phrase “the evil one” is a reference to Satan. The genitive noun τοῦ πονηροῦ (tou ponhrou) is ambiguous with regard to gender: It may represent the neuter τὸ πονηρόν (to ponhron), “that which is evil,” or the masculine ὁ πονηρός (Jo ponhro"), “the evil one,” i.e., Satan. In view of the frequent use of the masculine in 1 John 2:13-14, 3:12, and 5:18-19 it seems much more probable that the masculine is to be understood here, and that Jesus is praying for his disciples to be protected from Satan. Cf. BDAG 851 s.v. πονηρός 1.b.β and 1.b.γ.
