John Gill Commentary Acts 19:12

"insomuch that unto the sick were carried away from his body handkerchiefs or aprons, and the evil spirits went out." — Acts 19:12 (ASV)

So that from his body were brought unto the sick
The Ethiopic version renders it, "from the extremity", or "border of his garment"; and the Syriac version, "from the garments which were upon his body"; were brought and put upon the sick; that is, of the clothes which the apostle wore, some of them were taken and carried to sick persons, and used by them: particularly "handkerchiefs" or "aprons"; the former were such as he might use to wipe his face with, and remove sweat, or any filth from the body; and the latter, what he might wear as a mechanic, when working at his trade:

and the diseases departed from them, and the evil spirits went out
of them ;
who were afflicted and possessed with them; these were some of the special and uncommon miracles wrought by the hands of the apostle, and which were wrought in an uncommon way; and which most clearly showed that they were wrought by a divine power.
