1 tn Grk “that this”; the referent (the promise mentioned in the previous verse) has been specified in the translation for clarity.
sn This promise refers to the promise of a Savior through the seed (descendants) of David that is proclaimed as fulfilled (Rom 1:1-7).
2 tn Or “by resurrecting.” The participle ἀναστήσας (anasthsa") is taken as instrumental here.
sn By raising (i.e., by resurrection) tells how this promise came to be realized, though again the wordplay also points to his presence in history through this event (see the note on “raised up” in v. 22).
3 sn You are my Son. The key to how the quotation is used is the naming of Jesus as “Son” to the Father. The language is that of kingship, as Ps 2 indicates. Here is the promise about what the ultimate Davidic heir would be.
4 tn Grk “I have begotten you.” The traditional translation for γεγέννηκα (gegennhka, “begotten”) is misleading to the modern English reader because it is no longer in common use. Today one speaks of “fathering” a child in much the same way speakers of English formerly spoke of “begetting a child.”
sn A quotation from Ps 2:7.
5 tn Grk “It happened that when.” The introductory phrase ἐγένετο (egeneto, “it happened that”), common in Luke (69 times) and Acts (54 times), is redundant in contemporary English and has not been translated.
6 tn Grk “When our days were over.” L&N 67.71 has “ὅτε δὲ ἐγένετο ἡμᾶς ἐξαρτίσαι τὰς ἡμέρας ‘when we brought that time to an end’ or ‘when our time with them was over’ Ac 21:5.”
7 tn Grk “accompanying.” Due to the length and complexity of the Greek sentence, a new sentence was begun in the translation and the participle προπεμπόντων (propempontwn) translated as a finite verb.
8 tn Grk “city, and after.” Because of the length of the Greek sentence, the conjunction καί (kai) has not been translated here. Instead a new English sentence is begun.
9 sn On praying in Acts, see 1:14, 24; 2:47; 4:23; 6:6; 10:2; 12:5, 12; 13:3; 16:25.
10 tn BDAG 511 s.v. κατά B.1.a has “τοὺς κ. τὰ ἔθνη ᾿Ιουδαίους the Judeans (dispersed) throughout the nations 21:21.” The Jews in view are not those in Palestine, but those who are scattered throughout the Gentile world.
11 tn Or “to forsake,” “to rebel against.” BDAG 120 s.v. ἀποστασία has “ἀποστασίαν διδάσκεις ἀπὸ Μωϋσέως you teach (Judeans) to abandon Moses Ac 21:21.”
sn The charge that Paul was teaching Jews in the Diaspora to abandon Moses was different from the issue faced in Acts 15, where the question was whether Gentiles needed to become like Jews first in order to become Christians. The issue also appears in Acts 24:5-6, 13-21; 25:8.
12 sn That is, not to circumcise their male children. Biblical references to circumcision always refer to male circumcision.
13 tn Grk “or walk.”
