Acts 21:25 -- James reminds Paul of the Acts 15 Apostolic Decree: the Gentiles only need the four abstentions. The Jew/Gentile distinction in the decree is explicitly restated.

The deliberate juxtaposition of Acts 21:24 (Paul keeping the law as a Jew) and Acts 21:25 (Gentiles only have the four commands) reinforces Winger's two-category reading: different standards for Jews and Gentiles.
