¹ tn The translation for ἰδεῖν (idein) in this verse is given by BDAG 279-80 s.v. εἶδον 3 as “deliberate concerning this matter.” A contemporary idiom would be to “look into” a matter.

² tn Although the word διελέξατο (dielexato; from διαλέγομαι, dialegomai) is frequently translated “reasoned,” “disputed,” or “argued,” this sense comes from its classical meaning where it was used of philosophical disputation, including the Socratic method of questions and answers. However, there does not seem to be contextual evidence for this kind of debate in Acts 18:4. As G. Schrenk (TDNT 2:94-95) points out, “What is at issue is the address which any qualified member of a synagogue might give.” Other examples of this may be found in the NT in Matt 4:23 and Mark 1:21.

³ sn See the note on synagogue in 6:9.

⁴ tn Grk “Addressing in the synagogue every Sabbath, he was attempting to persuade both Jews and Greeks.” Because in English the verb “address” is not used absolutely but normally has an object specified, the direct objects of the verb ἔπειθεν (epeiqen) have been moved forward as the objects of the English verb “addressed,” and the pronoun “them” repeated in the translation as the object of ἔπειθεν. The verb ἔπειθεν has been translated as a conative imperfect.

⁵ tn BDAG 233 s.v. διαμαρτύρομαι 1 has “testify of, bear witness to (orig. under oath)…of repentance to Judeans and Hellenes Ac 20:21.”

⁶ tc Several mss, including some of the more important ones (Ì⁷⁴ א Α C [D] E 33 36 323 945 1175 1241 1505 1739 pm and a number of versions), read Χριστόν (Criston, “Christ”) at the end of this verse. This word is lacking in B H L P Ψ 614 pm. Although the inclusion is supported by many earlier and better mss, internal evidence is on the side of the omission: In Acts, both “Lord Jesus” and “Lord Jesus Christ” occur, though between 16:31 and the end of the book “Lord Jesus Christ” appears only in 28:31, perhaps as a kind of climactic assertion. Thus, the shorter reading is to be preferred.

sn Repentance toward God and faith in our Lord Jesus. Note the twofold description of the message. It is a turning to God involving faith in Jesus Christ.
