1 tn Grk “brothers,” but the Greek word may be used for “brothers and sisters” or “fellow Christians” as here (cf. BDAG 18 s.v. ἀδελφός 1., where considerable nonbiblical evidence for the plural ἀδελφοί [adelfoi] meaning “brothers and sisters” is cited).
2 tn Grk “make your calling and election sure.”
sn Make sure of your calling and election. The author is not saying that virtue and holiness produce salvation, but that virtue and holiness are the evidence of salvation.
3 tn Grk “these things.”
4 tn In Greek οὐ μή (ou mh) followed by the subjunctive is normally the strongest way to negate an action. Coupled with πότε (pote, “ever”), the statement is even more emphatic. The author is offering sage advice on how to grow in grace.
5 tn The words “into sin” are not in the Greek text, but the Greek word πταίω (ptaiw) is used in soteriological contexts for more than a mere hesitation or stumbling. BDAG 894 s.v. 2 suggests that here it means “be ruined, be lost,” referring to loss of salvation, while also acknowledging that the meaning “to make a mistake, go astray, sin” is plausible in this context. Alternatively, the idea of πταίω here could be that of “suffer misfortune” (so K. L. Schmidt, TDNT 6:884), as a result of sinning.
6 tn Grk “knowing this [to be] foremost.” Τοῦτο πρῶτον (touto prwton) constitute the object and complement of γινώσκοντες (ginwskonte"). The participle is loosely dependent on the infinitive in v. 2 (“[I want you] to recall”), perhaps in a telic sense (thus, “[I want you] to recall…[and especially] to understand this as foremost”). The following statement then would constitute the main predictions with which the author was presently concerned. An alternative is to take it imperativally: “Above all, know this.” In this instance, however, there is little semantic difference (since a telic participle and imperatival participle end up urging an action). Cf. also 2 Pet 1:20.
7 tn The Greek reads “scoffers in their scoffing” for “blatant scoffers.” The use of the cognate dative is a Semitism designed to intensify the word it is related to. The idiom is foreign to English. As a Semitism, it is further incidental evidence of the authenticity of the letter (see the note on “Simeon” in 1:1 for other evidence).
8 tn Grk “going according to their own evil urges.”
