1 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.
2 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.
3 sn That is, not to circumcise their male children. Biblical references to circumcision always refer to male circumcision.
4 tn Grk “or walk.”
5 sn That is, undergo ritual cleansing. Paul’s cleansing would be necessary because of his travels in “unclean” Gentile territory. This act would represent a conciliatory gesture. Paul would have supported a “law-free” mission to the Gentiles as an option, but this gesture would represent an attempt to be sensitive to the Jews (1 Cor 9:15-22).
6 tn L&N 57.146 has “δαπάνησον ἐπ᾿ αὐτοῖς ‘pay their expenses’ Ac 21:24.”
7 tn The future middle indicative has causative force here. BDAG 686 s.v. ξυράω has “mid. have oneself shaved…τὴν κεφαλήν have one’s head shaved…Ac 21:24.”
sn Having their heads shaved probably involved ending a voluntary Nazirite vow (Num 6:14-15).
8 tn Grk “and.” Because of the length and complexity of the Greek sentence, a new sentence was begun in the translation, and καί (kai) has been translated as “then” to indicate the logical sequence.
9 tn The verb here describes a report or some type of information (BDAG 534 s.v. κατηχέω 1).
10 tn Grk “adhere to the keeping of the law.” L&N 41.12 has “στοιχέω: to live in conformity with some presumed standard or set of customs – ‘to live, to behave in accordance with.’”
11 sn The law refers to the law of Moses.
