¹ tn The term πονηροῦ (ponhrou) may be understood as specific and personified, referring to the devil, or possibly as a general reference to evil. It is most likely personified, however, since it is articular (τοῦ πονηροῦ, tou ponhrou). Cf. also “the evildoer” in v. 39, which is the same construction.

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.

¹ sn Since the author states that Cain…was of the evil one (ἐκ τοῦ πονηροῦ, ek tou ponhrou), in the immediate context this imagery serves as an illustration of 3:8a: The person who practices sin is of the devil (ἐκ τοῦ διαβόλου, ek tou diabolou). This is similar to John 8:44, where Jesus told his opponents “you people are from your father the devil…[who] was a murderer from the beginning.” In both Jewish and early Christian writings Cain is a model for those who deliberately disbelieve; Testament of Benjamin 7:5 looks forward to the punishment of those who “are like Cain in the envy and hatred of brothers.” It is not difficult to see why the author of 1 John used Cain here as a model for the opponents in light of their failure to “love the brothers” (see 1 John 3:17).
