Acts 19:22

Timothy and Erastus (not the Erastus of Romans 16:23) were sent, partly to remind the Churches of Europe of the teaching and example of St. Paul, and partly to collect money for the poor saints at Jerusalem (Acts 24:17; 1 Corinthians 16:1; 1 Corinthians 16:10). Shortly after this 1 Corinthians was written.

23f. St. Luke mentions no persecutions or trials until the close of the Ephesian niinistry, yet we know that though 'a great door and effectual' was opened to the Apostle, yet there were 'many adversaries' (1 Corinthians 16:9); that he was in daily danger of death (Acts 15:30); that Prisca and Aquila to save his life 'laid down their own necks' (Romans 16:3); and that he 'fought with beasts,' i.e. savage enemies (1 Corinthians 15:32).
