Discovery BoxActs 21:24 
Context21:24 take them and purify 1 yourself along with them and pay their expenses, 2 so that they may have their heads shaved. 3 Then 4 everyone will know there is nothing in what they have been told 5 about you, but that you yourself live in conformity with 6 the law. 7
Acts 21:26
Context21:26 Then Paul took the men the next day, 8 and after he had purified himself 9 along with them, he went to the temple and gave notice 10 of the completion of the days of purification, 11 when 12 the sacrifice would be offered for each 13 of them.
1 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).
2 tn L&N 57.146 has “δαπάνησον ἐπ᾿ αὐτοῖς ‘pay their expenses’ Ac 21:24.”
3 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).
4 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.
5 tn The verb here describes a report or some type of information (BDAG 534 s.v. κατηχέω 1).
6 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.’”
7 sn The law refers to the law of Moses.
8 tn BDAG 422 s.v. ἔχω 11.b.β has “temporal, to be next, immediately following…τῇ ἐχομένῃ…on the next day Lk 13:33…Ac 20:15; w. ἡμέρᾳ added…21:26.”
9 tn That is, after he had undergone ritual cleansing. The aorist passive participle ἁγνισθείς (Jagnisqei") has been taken temporally of antecedent action.
10 tn Grk “entered the temple, giving notice.” The participle διαγγέλλων (diangellwn) has been translated as a finite verb due to requirements of contemporary English style.
11 sn The days of purification refers to the days of ritual cleansing.
12 tn Grk “until” (BDAG 423 s.v. ἕως 1.b.β.א), but since in English it is somewhat awkward to say “the completion of the days of purification, until the sacrifice would be offered,” the temporal clause was translated “when the sacrifice would be offered.” The point is that the sacrifice would be offered when the days were completed. Paul honored the request of the Jewish Christian leadership completely. As the following verse makes clear, the vow was made for seven days.
13 tn Grk “for each one.”
