Acts 19:22

So he sent into Macedonia - He desired Timothy to go as far as Corinth, 1 Corinthians 4:18 , and after that to return to him at Ephesus, 1 Corinthians 16:11 ; but he himself continued in Asia some time longer; probably to make collections for the poor saints in Jerusalem. Erastus, mentioned here for the first time, appears to have been the chamberlain, οικονομος , either of Ephesus or Corinth; see Romans 16:23 . He was one of St. Paul's companions, and is mentioned as being left by the apostle at Corinth, 2 Timothy 4:20 .
