1 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.
2 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).
3 tn Grk “going according to their own evil urges.”
4 tn Grk “knowing beforehand.”
5 tn Or “lawless ones.”
sn These unprincipled men. The same word is used in 2:7, suggesting further that the heretics in view in chapter 3 are the false teachers of chapter 2.
6 tn Grk “fall from your firmness.”
