¹ tn Grk “knowing this [to be] foremost.” Τοῦτο πρῶτον (touto prwton) constitute the object and complement of γινώσκοντες (ginwskonte"). The participle is dependent on the main verb in v. 19 (“you do well [if you pay attention]”), probably in a conditional usage. An alternative is to take it imperativally: “Above all, know this.” In this rendering, πρῶτον is functioning adverbially. Only here and 2 Pet 3:3 is τοῦτο πρῶτον found in the NT, making a decision more difficult.

² tn The ὅτι (Joti) clause is appositional (“know this, that”). English usage can use the colon with the same force.

³ tn Verse 20 is variously interpreted. There are three key terms here that help decide both the interpretation and the translation. As well, the relation to v. 21 informs the meaning of this verse. (1) The term “comes about” (γίνεται [ginetai]) is often translated “is a matter” as in “is a matter of one’s own interpretation.” But the progressive force for this verb is far more common. (2) The adjective ἰδίας (idias) has been understood to mean (a) one’s own (i.e., the reader’s own), (b) its own (i.e., the particular prophecy’s own), or (c) the prophet’s own. Catholic scholarship has tended to see the reference to the reader (in the sense that no individual reader can understand scripture, but needs the interpretations handed down by the Church), while older Protestant scholarship has tended to see the reference to the individual passage being prophesied (and hence the Reformation doctrine of analogia fidei [analogy of faith], or scripture interpreting scripture). But neither of these views satisfactorily addresses the relationship of v. 20 to v. 21, nor do they do full justice to the meaning of γίνεται. (3) The meaning of ἐπίλυσις (epilusi") is difficult to determine, since it is a biblical hapax legomenon. Though it is sometimes used in the sense of interpretation in extra-biblical Greek, this is by no means a necessary sense. The basic idea of the word is unfolding, which can either indicate an explanation or a creation. It sometimes has the force of solution or even spell, both of which meanings could easily accommodate a prophetic utterance of some sort. Further, even the meaning explanation or interpretation easily fits a prophetic utterance, for prophets often, if not usually, explained visions and dreams. There is no instance of this word referring to the interpretation of scripture, however, suggesting that if interpretation is the meaning, it is the prophet’s interpretation of his own vision. (4) The γάρ (gar) at the beginning of v. 21 gives the basis for the truth of the proposition in v. 20. The connection that makes the most satisfactory sense is that prophets did not invent their own prophecies (v. 20), for their impulse for prophesying came from God (v. 21).

sn No prophecy of scripture ever comes about by the prophet’s own imagination. 2 Pet 1:20-21, then, form an inclusio with v. 16: The Christian’s faith and hope are not based on cleverly concocted fables but on the sure Word of God – one which the prophets, prompted by the Spirit of God, spoke. Peter’s point is the same as is found elsewhere in the NT, i.e., that human prophets did not originate the message, but they did convey it, using their own personalities in the process.

⁴ tn The Greek is one long conditional sentence, from v. 4 to v. 10a. 2Pet 2:4-8 constitute the protasis; vv. 9 and 10a, the apodosis. In order to show this connection more clearly, a resumptive summary protasis – “if so,” or “if God did these things” – is needed in English translation.

⁵ tn Grk “from trial,” or possibly “from temptation” (though this second meaning for πειρασμός (peirasmo") does not fit the context in which Noah and Lot are seen as in the midst of trials, not temptation).

⁶ tn The adverbial participle κολαζομένους (kolazomenou") can refer either to contemporaneous time or subsequent time. At stake is the meaning of the following prepositional phrase (at the day of judgment or until the day of judgment). If the participle is contemporaneous, the idea is “to keep the ungodly in a state of punishment until the day of judgment.” If subsequent, the meaning is “to keep the ungodly to be punished at the day of judgment.” Many commentators/translations opt for the first view, assuming that the present participle cannot be used of subsequent time. However, the present participle is the normal one used for result, and is often used of purpose (cf., e.g., for present participles suggesting result, Mark 9:7; Luke 4:15; John 5:18; Eph 2:15; 2 Pet 2:1, mentioned above; for present participles indicating purpose, note Luke 10:25; John 12:33; Acts 3:26; 2 Pet 2:10 [as even most translations render it]). Further, the context supports this: 2:1-10 forms something of an inclusio, in which the final end of the false teachers is mentioned specifically in v. 1, then as a general principle in v. 9. The point of v. 3 – that the punishment of the false teachers is certain, even though the sentence has not yet been carried out, is underscored by a participle of purpose in v. 9.
