Acts 19:22 - Coke's Commentary on the Holy Bible

Timotheus and Erastus:— Timothy was a person very proper to be employed on this occasion; not only on account of his excellent character, but also as he had formerly been at Macedonia with St. Paul, and had assisted in planting the churches there. Erastus, who was joined with him, was chamberlain at Corinth; and they were charged with a commission to promote the collection which St. Paul was making, both in the European and Asiatic churches, for the poor Christians in Judea; which is afterwards so largely urged in the second epistle to the Corinthians, ch. 8 and 9.
