Eric Zafran ("Jan Victors & the Bible," Israel Museum News, 12, 1977) suggested that Jan Victors' unusual restriction to Old Testament subjects might have been to satisfy a specialised Jewish art market, growing ever more confident in 17th century Amsterdam.

Mosseh Vaz Farroh had a range of top flight Dutch and Flemish paintings, especially portraits.
