¹ sn By this refers to the righteous deeds mentioned at the end of 3:18, the expressions of love. It is by doing these deeds that believers assure themselves that they belong to the truth because the outward action reflects the inward reality of their relationship with God. Put another way, ‘conduct is the clue to paternity.’

² 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.

¹ tn The Greek is one long conditional sentence, from v. 4 to v. 10a. 2 Pet 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 “that one’s.” That is, “eyewitnesses of the grandeur of that one.” The remote demonstrative pronoun is used perhaps to indicate esteem for Jesus. Along these lines it is interesting to note that “the Pythagoreans called their master after his death simply ἐκεῖνος” as a term of reverence and endearment (BDAG 302 s.v. ἐκεῖνος a.γ).

⁴ tn Verses 22-23 are a single sentence in the Greek text. To improve clarity (and because contemporary English tends to use shorter sentences) these verses have been divided into three sentences in the translation. In addition, “So” has been supplied at the beginning of the second English sentence (v. 22b) to indicate the relationship with the preceding statement.

¹ sn The phrase in a son is the fulcrum of Heb 1:1-4. It concludes the contrast of God’s old and new revelation and introduces a series of seven descriptions of the Son. These descriptions show why he is the ultimate revelation of God.

¹ sn The overseer is another term for the same official position of leadership as the “elder.” This is seen in the interchange of the two terms in this passage and in Acts 20:17, 28, as well as in the parallels between these verses and 1 Tim 3:1-7.

² sn God our Savior. Use of the title “Savior” for God the Father is characteristic of 1 Timothy, 2 Timothy, and Titus. It occurs six times in these letters, but only twice elsewhere in the NT. However, it occurs commonly in the OT, especially in Isaiah. It emphasizes the Father as the initiator and source of salvation.

² tn The ἵνα (hina) clause has been rendered as substantival here, indicating the content of the prayer rather than the purpose for it. These two ideas are very similar and difficult to differentiate in this passage, but the conjunction ἵνα following a verb of praying is generally regarded as giving the content of the prayer.

² tn Grk “reveal this to you.” The referent of the pronoun “this” is the fact that the person is thinking differently than Paul does. This has been specified in the translation with the phrase “the error of your ways”; Paul is stating that God will make it known to these believers when they are not in agreement with Paul.

⁵ sn Eph 1:19-20. The point made in these verses is that the power required to live a life pleasing to God is the same power that raised Christ from the dead. For a similar thought, cf. John 15:1-11.

¹ tn Paul is probably referring to scars from wounds received in the service of Jesus, although the term στίγμα (stigma) may imply ownership and suggest these scars served as brands (L&N 8.55; 33.481; 90.84).

¹ tn Paul’s use of the Greek article here and before the phrase “free woman” presumes that both these characters are well known to the recipients of his letter. This verse is given as an example of the category called “well-known (‘celebrity’ or ‘familiar’) article” by ExSyn 225.

¹ tn The NA²⁸ Greek text, NRSV, NJB, TEV, HCSB, and a few others place the phrase “I have been crucified with Christ” at the end of v. 19, but most English translations place these words at the beginning of v. 20.

¹ sn Beaten with a rod refers to the Roman punishment of admonitio according to BDAG 902 s.v. ῥαβδίζω. Acts 16:22 describes one of these occasions in Philippi; in this case it was administered by the city magistrates, who had wide powers in a military colony.

¹ tn Or “must do.” The words “of you” and “should give” are not in the Greek text, which literally reads, “Each one just as he has decided in his heart.” The missing words are an ellipsis; these or similar phrases must be supplied for the English reader.

¹ sn “Everything is lawful.” Here again Paul cites certain slogans the Corinthians used to justify their behavior (cf. 6:12-13; 7:1; 8:1, 4). Paul agrees with the slogans in part, but corrects them to show how the Corinthians have misused these ideas.

¹ sn “We all have knowledge.” Here and in v. 4 Paul cites certain slogans the Corinthians apparently used to justify their behavior (cf. 6:12-13; 7:1; 10:23). Paul agrees with the slogans in part, but corrects them to show how the Corinthians have misused these ideas.

¹ sn “An idol in this world is nothing” and “There is no God but one.” Here and in v. 1 Paul cites certain slogans the Corinthians apparently used to justify their behavior (cf. 6:12-13; 7:1; 10:23). Paul agrees with the slogans in part, but corrects them to show how the Corinthians have misused these ideas.

¹ sn All things are lawful for me. In the expressions in vv. 12-13 within quotation marks, Paul cites certain slogans the Corinthians apparently used to justify their behavior. Paul agrees with the slogans in part, but corrects them to show how the Corinthians have misused these ideas.
