Verse 4
Trophimus: Acts 20:4, Acts 21:29 an Asian co-worker apparently of Ephesus. One of eight friends who accompanied Paul at the end of the 3rd missionary journey.[ see 1 Corinthians 16:3-4; 2 Corinthians 8:19-20 ] He was the innocent cause of the riot in the Jewish Temple that almost cost Paul his life.
None from Corinth are list in Acts 20:4, where the representatives to Jerusalem with this offering are mentioned. Some have asserted that it was possible that Titus, who went earlier, was their representative, but there is no mention of him in Acts. cf. 1 Corinthians 16:3-4; 2 Corinthians 8:19-20.
(See 2 Corinthians 12:16 and context where Paul seems to have accused to planing to steal this money by deceit.)
