John Gill Commentary Acts 19:24

"For a certain man named Demetrius, a silversmith, who made silver shrines of Diana, brought no little business unto the craftsmen;" — Acts 19:24 (ASV)

For a certain man, named Demetrius, a silversmith
Who worked in silver, not in coining silver money, but in making silver vessels, in melting silver, and casting it into moulds, and forming it into different shapes; and particularly,

which made silver shrines for Diana ;
who Diana was, (See Gill on Acts 19:27), these were not coins or medals of silver, struck by Demetrius, with the figure of the temple of Diana on them, nor images of Diana, as the Ethiopic version reads; but they were chaplets, or little temples made of silver, in imitation of the temple of Diana at Ephesus, with her image included in it; the words may be rendered, "silver temples": in some manuscripts it is added, "like little chests": which being sold to the people,

brought no small gain to the craftsmen :
who were of the same trade with him; masters of the same business, who employed others under them, as appears by what follows.
