Decree, issued by the German Department of the Interior [Present-day Germany]: “While incarcerated Jewish criminals may, where this is feasible, partake in the religious rituals of their brothers in faith, or even, on Christian Sundays and holidays, when no labor is done, convene in a designated room to read their law and psalm books, they are, however, not released from working on Saturdays.” [Researcher’s note: The Jewish day of rest, Shabbat, falls on Saturday.]
