Chapter 19
[Acts 19:9-10] -- He separated the disciples, daily disputing in the school of a certain Tyrannus. This happened for three years, etc. At this time, while Paul was staying in Ephesus, it is said that he wrote the first letter to the Corinthians, in which he also mentions Priscilla and Aquila, saying: "Aquila and Priscilla greet you much in the Lord, with the church that is in their house" (1 Cor. XVI). By this word it is also shown that not only did they serve Christ faithfully, but also had a congregation of faithful in their house. Furthermore, the second epistle is said to have been written when he was in Troas: Moreover, the Epistle to the Romans was written later as the record shows. For he himself testifies that he wrote it on his journey to Jerusalem.
[Acts 19:12] -- So that even handkerchiefs or aprons that had touched his skin were carried to the sick. Many of us do not know what aprons signify; however, Gregory, who is now the bishop of the Apostolic See, while he was still an archdeacon, answered a friend from Britain who inquired about this among other things, that it is a kind of handkerchief which the Hebrews use on their heads.
