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 “defilements”; “contaminations”; “pollutions.”
5 sn Through the rich knowledge of our Lord and Savior Jesus Christ. The implication is not that these people necessarily knew the Lord (in the sense of being saved), but that they were in the circle of those who had embraced Christ as Lord and Savior.
6 tn Grk “(and/but) they.”
7 tn Grk “they again, after becoming entangled in them, are overcome by them.”
