⁴ tn This is the same confession as in 1 John 4:2 except the perfect participle used there is replaced by a present participle (ἐρχόμενον, erchomenon) here. It is not clear why the author changed from a perfect participle in 1 John 4:2 to a present participle here. The perfect participle suggests a reference to the incarnation (past). The present participle could suggest a reference to the (future) second advent, but based on the similarity to 1 John 4:2 it is probably best to take it as referring to the incarnation.

¹ tn Once more there is the familiar difficulty of determining whether the phrase refers (1) to what precedes or (2) to what follows. Here, because ἐν τούτῳ (en toutō) is followed by a clause introduced by ὅταν (hotan) which appears to be related, it is best to understand ἐν τούτῳ as referring to what follows. The following ὅταν clause is epexegetical to ἐν τούτῳ, explaining how we know that we love God’s children: “by this we know that we love God’s children, whenever we love God and keep his commandments.”

¹ tn The interpretation of the three ὅτι clauses in v. 21 is very difficult: (1) All three instances of ὅτι (hoti) may be causal (so NASB, NIV, NEB). (2) The first two may be causal while the third indicates content (declarative or recitative ὅτι, so KJV, RSV, TEV, NRSV). (3) However, it is best to take all three instances as indicating content because this allows all three to be subordinate to the verb ἔγραψα (egrapsa) as compound direct objects. The author writes to reassure his readers (a) that they do indeed know the truth (first two uses of ὅτι) and (b) that no lie is of the truth (third use).

⁶ tn This cryptic expression has been variously interpreted. (1) It could involve a simple cognate dative in which case the idea is “they will be utterly destroyed.” But the presence of αὐτῶν (autōn; their, of them) is problematic for this view. Other, more plausible views are: (2) the false teachers will be destroyed at the same time as the irrational beasts, or (3) in the same manner as these creatures (i.e., by being caught); or (4) the false teachers will be destroyed together with the evil angels whom they insult. Because of the difficulties of the text, it was thought best to leave it ambiguous, as the Greek has it.

² tn The participle is either means (“by making every effort”) or attendant circumstance (“make every effort”). Although it fits the normal contours of attendant circumstance participles, the semantics are different. Normally, attendant circumstance is used of an action that is a necessary prelude to the action of the main verb. But “making every effort” is what energizes the main verb here. Hence it is best taken as means. However, for the sake of smoothness the translation has rendered it as a command with the main verb translated as an infinitive. This is in accord with English idiom.

¹ tc The majority of mss, especially the later ones (א² 0278^vid 1739 M lat), have ὁ θεός (ho theos, “God”) at this point, while most of the earliest and best witnesses lack such an explicit addressee (so P⁴⁶ א* A C D K P Ψ 33 1175 1881 2464 al). The longer reading is apparently motivated in part by the wording of Ps 40:8 (39:9 LXX) and by the word order of this same verse as quoted in Heb 10:7.

⁴ tc ‡ Most texts, including some early and significant ones (א² A B* D Ψ 0122 0278 1881 M sy Cl), have καί (kai, “and”) immediately preceding οὐ (ou, “not”), but other equally significant witnesses (P⁴⁶ א* B² C 33 81 1739 lat Or Did) lack the conjunction. As it was a natural tendency for scribes to add a coordinating conjunction, the καί appears to be a motivated reading. On balance, it is probably best to regard the shorter reading as authentic. NA²⁸ has καί in brackets, indicating doubts as to its authenticity.

¹ tn The phrase begins with the ἵνα (hina) clause and is subordinate to the imperative προσκαρτερεῖτε (proskartereite) in v. 2. The reference to the idea that Paul must make it known indicates that this clause is probably best viewed as purpose and not content, like the ἵνα of v. 3. It is the second purpose stated in the context; the first is expressed through the infinitive λαλῆσαι (lalēsai) in v. 3. The term “pray” at the beginning of the sentence is intended to pick up the imperative of v. 3.

³ tc παραδόσεων (paradoseōn; “traditions, commandments”) is read by D*, while the vast majority of witnesses read παραβάσεων (parabaseōn, “transgressions”). D’s reading makes little sense in this context. πράξεων (praxeōn, “of deeds”) replaces παραβάσεων in P⁴⁶ F G it Ir^lat Ambst Spec. The wording is best taken as going with νόμος (nomos; “Why then the law of deeds?”), as is evident by the consistent punctuation in the later witnesses. But such an expression is unpauline and superfluous; it was almost certainly added by some early scribe(s) to soften the blow of Paul’s statement.

¹ tn The Greek word ῥιπή (rhipē) refers to a very rapid movement (BDAG 906 s.v.). This has traditionally been translated as “twinkling,” which implies an exceedingly fast—almost instantaneous—movement of the eyes, but this could be confusing to the modern reader since twinkling in modern English often suggests a faint, flashing light. In conjunction with the genitive ὀφθαλμοῦ (ophthalmou, “of an eye”), “blinking” is the best English equivalent (see, e.g., L&N 16.5), although it does not convey the exact speed implicit in the Greek term.

¹ tc Grk “the brother.” Later witnesses (א² D² M) have ἀνδρί (andri, “husband”) here, apparently in conscious emulation of the earlier mention of ἀνήρ (anēr) in the verse. However, the earliest and best witnesses (P⁴⁶ א* A B C D* F G P Ψ 33 1739 al co) are decisively in favor of ἀδελφῷ (adelphō, “brother”), a word that because of the close association with “wife” here may have seemed inappropriate to many scribes. It is also for reasons of English style that “her husband” is used in the translation.

² tc The shorter reading, κυρίου (kuriou, “Lord”), is found in P⁴⁶ B 630 1739; κυρίου ᾿Ιησοῦ (kuriou Iēsou, “Lord Jesus”) is read by P^61vid א Ψ M; κυρίου ᾿Ιησοῦ Χριστοῦ (kuriou Iēsou Christou, “Lord Jesus Christ”) by D; and κυρίου ἡμῶν ᾿Ιησοῦ Χριστοῦ (kuriou hēmōn Iēsou Christou, “our Lord Jesus Christ”) by A F G P 33 al. The shorter reading is preferred as the reading that best explains the other readings, especially in view of the mention of “Jesus” twice in the previous verse.

¹ tc ‡ Some Alexandrian and Byzantine mss (P^94vid א* B C 81 365 1506 1739 1881) have the infinitive “to be” (εἶναι, einai) following “yourselves”. The infinitive is lacking from some mss of the Alexandrian and Western textual clusters (P^46vid A D*^,c F G 33). The infinitive is found elsewhere in the majority of Byzantine mss, suggesting a scribal tendency toward clarification. The lack of infinitive best explains the rise of the other readings. The meaning of the passage is not significantly altered by inclusion or omission, but on internal grounds omission is more likely. NA²⁸ includes the infinitive in brackets, indicating doubt as to its authenticity.

¹ tc ‡ There is some dispute over whether τῇ πίστει is here or not. Several decent witnesses lack the words (B D F G 0220 sa Ambst) while they are found (with ἐν preceding the article in some) in other witnesses, some of which are very good (א [+ ἐν in א¹; lacking in א*, omitted in א^c] A [also with ἐν] C Ψ 33 1739 1881 lat). On balance, the shorter reading has stronger external witnesses. As well, (ἐν) τῇ πίστει strikes the reader as mildly redundant and certainly as a clarification. As such, it seems to be a motivated reading. It is thus best to delete the words from the text.

⁵ tc Some later mss include 28:29: “When he had said these things, the Jews departed, having a great dispute among themselves.” Verse 29 is lacking in P^74vid א A B E Ψ 048 33 81 1175 1739 2464 and a number of versions. They are included (with a few minor variations) in M it and some versions. This verse is almost certainly not a part of the original text of Acts, as it lacks the best credentials. The present translation follows NA²⁸ in omitting the verse number, a procedure also followed by a number of other modern translations.

¹ tc A few early mss (א* B Ψ [gig] sa [bo]) read περιελόντες (perielontes, “[From there we] cast off [and arrived at Rhegium]”; cf. Acts 27:40). The other major variant, περιελθόντες (perielthontes, “[we] sailed from place to place”), is found in P⁷⁴ א² A 066 1739 M lat sy. Although περιελόντες is minimally attested, it is found in the better witnesses. As well, it is a more difficult reading, for its meaning as a nautical term is uncertain, requiring something like “τὰς ἀγκύρας be supplied = ‘we weighed anchor’” (BDAG 799 s.v. περιαιρέω 1). It thus best explains the rise of the other readings.

¹ tn Or “began to harm [the church] severely.” If the nuance of this verb is “destroy,” then the imperfect verb ἐλυμαίνετο (elumaineto) is best translated as a conative imperfect as in the translation above. If instead the verb is taken to mean “injure severely” (as L&N 20.24), it should be translated in context as an ingressive imperfect (“began to harm the church severely”). Either option does not significantly alter the overall meaning, since it is clear from the stated actions of Saul in the second half of the verse that he intended to destroy or ravage the church.

³ sn The crown of thorns was a crown plaited of some thorny material, intended as a mockery of Jesus’ “kingship.” Traditionally it has been regarded as an additional instrument of torture, but it seems more probable the purpose of the thorns was not necessarily to inflict more physical suffering but to imitate the spikes of the “radiant corona,” a type of crown portrayed on ruler’s heads on many coins of the period; the spikes on this type of crown represented rays of light pointing outward (the best contemporary illustration is the crown on the head of the Statue of Liberty in New York harbor).

³ sn The time has come. Jesus has said before that his “hour” had come, both in 12:23 when some Greeks sought to speak with him, and in 13:1 where just before he washed the disciples’ feet. It appears best to understand the “hour” as a period of time starting at the end of Jesus’ public ministry and extending through the passion week, ending with Jesus’ return to the Father through death, resurrection, and exaltation. The “hour” begins as soon as the first events occur which begin the process that leads to Jesus’ death.

³ sn You both know me and know where I come from! Jesus’ response while teaching in the temple is difficult—it appears to concede too much understanding to his opponents. It is best to take the words as irony: “So you know me and know where I am from, do you?” On the physical, literal level, they did know where he was from: Nazareth of Galilee (at least they thought they knew). But on another deeper (spiritual) level, they did not: He came from heaven, from the Father. Jesus insisted that he has not come on his own initiative (cf. 5:37), but at the bidding of the Father who sent him.
