[12:7] 1 tn Grk “Leave her alone, that for the day of my burial she may keep it.” The construction with ἵνα (Jina) is somewhat ambiguous. The simplest way to read it would be, “Leave her alone, that she may keep it for the day of my burial.” This would imply that Mary was going to use the perfumed oil on that day, while vv. 3 and 5 seem to indicate clearly that she had already used it up. Some understand the statement as elliptical: “Leave her alone; (she did this) in order to keep it for the day of my burial.” Another alternative would be an imperatival use of ἵνα with the meaning: “Leave her alone; let her keep it.” The reading of the Byzantine text, which omits the ἵνα and substitutes a perfect tense τετήρηκεν (tethrhken), while not likely to be original, probably comes close to the meaning of the text, and that has been followed in this translation.
[17:15] 2 tn Or “that you protect them”; Grk “that you keep them.”
[17:15] 3 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.
