² tn The present imperative περιπατεῖτε (peripateite) implies, in this context, a continuation of something already begun. This is evidenced by the fact that Paul has already referred to their faith as “orderly” and “firm” (2:5), despite the struggles of some of them with this deceptive heresy (cf. 2:16-23). The verb is used literally to refer to a person “walking” and is thus used metaphorically (i.e., ethically) to refer to the way a person lives his or her life.

¹ sn Down payment. The Greek word ἀρραβών (arrabōn) denotes the first payment or first installment of money or goods which serves as a guarantee or pledge for the completion of the transaction. In the NT the term is used only figuratively of the Holy Spirit as the down payment of the blessings promised by God (it is used also in 2 Cor 1:22 and 5:5). In the “already—not yet” scheme of the NT the possession of the Spirit now by believers (“already”) can be viewed as a guarantee that God will give them the balance of the promised blessings in the future (“not yet”).

¹ sn Down payment. The Greek word ἀρραβών (arrabōn) denotes the first payment or first installment of money or goods which serves as a guarantee or pledge for the completion of the transaction. In the NT the term is used only figuratively of the Holy Spirit as the down payment of the blessings promised by God (it occurs later in 2 Cor 5:5, and also in Eph 1:14). In the “already—not yet” scheme of the NT the possession of the Spirit now by believers (“already”) can be viewed as a guarantee that God will give them the balance of the promised blessings in the future (“not yet”).

² tn The perfect tense verb הָיָה (hayah) refers to a past perfect situation: It describes an action that is viewed as a remote past event from the perspective of the past. This past perfect situation is brought out by the temporal adverb כְּבָר (k^evar, “already”; HALOT 459 s.v. I כְּבָר; BDB 460 s.v. I כְּבָר; cf. 1:10; 2:12, 16; 3:15; 4:2; 6:10; 9:6-7). The expression כְּבָר plus הָיָה connotes a past perfect nuance: “it has already been” (Eccl 1:10; see BDB 460 s.v.).

¹ tn Grk “honor,” but BDAG 1005 s.v. τιμή 2.b states, “An outstanding feature of the use of τ., as already shown in several passages, is its combination w. δόξα…of earthly possessions τὴν δόξαν καὶ τὴν τιμὴν τῶν ἐθνῶν Rv 21:26 (τιμή concr.=an object of value: Ezk 22:25).”

¹ tn The author has already described Gaius as “dear friend” or “beloved” (τῷ ἀγαπητῷ, tō agapētō) in v. 1; he will address Gaius in the same way in vv. 5 and 11 (᾿Αγαπητέ, Agapēte). This is a term of endearment and personal warmth, much as it is when used by the author as an address in 1 John 2:7.

² tn BDAG 821 s.v. πιστός 1.b offers the translation “act loyally” for this context, a usage which is not common but does fit well here. Since the author is going to ask Gaius for additional help for these missionaries in the following verse, he begins here by commending Gaius for all that he has already done in this regard.

¹ tn The introductory καὶ νῦν (kai nun) has some adversative (contrastive) force: The addressees are already “living according to the truth” (v. 4) but in the face of the threat posed by the opponents, the author has to stress obedience all the more.

¹ tn Grk “I am already writing this [as] a second letter.” The object-complement construction is more smoothly rendered in English a bit differently. Further, although the present tense γράφω (graphō) is used here, English convention employs an epistolary past tense. (The Greek epistolary aorist might have been expected here, but it also occurs in situations unlike its English counterparts.)

⁶ sn The term grandeur was used most frequently of God’s majesty. In the 1st century, it was occasionally used of the divine majesty of the emperor. 2 Pet 1:1 and 1:11 already include hints of a polemic against emperor-worship (in that “God and Savior” and “Lord and Savior” were used of the emperor).

⁴ sn The point of the knowledge of him has nothing to do with what God knows, but with what believers are to know (hence, “your…knowledge”). Further, the author’s prayer is that this knowledge of God would increase, not simply be initiated, since he is writing to believers who already know God (hence, “your growing knowledge of him”).

² tn Verse 3 is one sentence in Greek (“For—even though I am absent in body, yet present in spirit—I have already judged the one who did this, as though I were present”) that has been broken up due to English stylistic considerations.

³ tn BDAG 866 s.v. προγινώσκω 2 has “Know from time past…προγινώσκοντές με ἄνωθεν Ac 26:5.” L&N 28.6 states, “‘they have already known me beforehand, if they are willing to testify’ Ac 26:5.”

⁵ tn BDAG 62 s.v. ἀνάγω 4 gives “put out to sea” here (as a nautical technical term). However, since the English expression “put out to sea” could be understood to mean Paul was already aboard the ship (which is not clear from the context), the simpler expression “sail” is used at this point in the translation.

² sn We know where this man comes from. The author apparently did not consider this objection worth answering. The true facts about Jesus’ origins were readily available for any reader who didn’t know already. Here is an instance where the author assumes knowledge about Jesus that is independent from the material he records.

¹ sn A denarius was a silver coin worth approximately one day’s wage for a laborer. The fact that the leaders had such a coin showed that they already operated in the economic world of Rome. The denarius would have had a picture of Tiberius Caesar, the Roman emperor, on it.

¹ tn Here καί (kai) has been translated as “but” to indicate the contrast present in this context. Those watching the evaluation are shocked, as the one with the most gets even more. The word “already” is supplied at the end of the statement to indicate this surprise and shock.

¹ sn You who hunger are people like the poor Jesus has already mentioned. The term has OT roots both in conjunction with the poor (Isa 32:6-7; 58:6-7, 9-10; Ezek 18:7, 16) or by itself (Pss 37:16-19; 107:9).

¹ sn Wineskins were bags made of skin or leather, used for storing wine in NT times. As the new wine fermented and expanded, it would stretch the new wineskins. Putting new (unfermented) wine in old wineskins, which had already been stretched, would result in the bursting of the wineskins.

² sn But the one who endures to the end will be saved. Jesus was not claiming here that salvation is by works because he had already taught that it is by grace (cf. 10:15). He was simply arguing that genuine faith evidences itself in persistence through even the worst of trials.
