Acts 16:12 establishes Philippi as a Roman colony — the basis for the accusers' appeal that these customs are unlawful for Romans.

Acts 17:7 repeats a similar accusation in Thessalonica — acting contrary to Caesar's decrees — showing a pattern of opposition.

Acts 26:3 highlights Agrippa's expertise in Jewish customs — the same customs deemed unlawful here by Roman accusers.

Esther 3:8 has Haman accuse Jews of different laws not keeping king's laws — a direct parallel to the accusation here.

Luke 23:2 records false accusations against Jesus before Pilate — echoed here as Paul is similarly charged with violating Roman customs.
