All of Kranz's works were published after his death by
Abraham Bär Flahm with the permission of Kranz's son
Yitzhak Kranz who found notes left over by the Maggid in
Mezritch where he had preached, and was able to piece together parts of some other books. • "Ohel Ya'akov", a homiletic commentary on the Pentateuch abounding with graphic parables (i.,
Józefów, 1830; ii., Zolkiev, 1837; iii.,
Vienna, 1863; iv., 1861; v., Vienna, 1859); • "Kol Ya'akov" (
Warsaw, 1819), a similar commentary on the Five Scrolls; • "Kochav mi-Ya'akov", a commentary on the "haftarot"; • "Emes le-Ya'akov" (Zolkiev, 1836), a commentary on the
Passover Haggadah; • "Sefer ha-Middos" (n.p., 1862), ethics arranged in eight "gates" or sections, each section being divided into several chapters. This work resembles very much the "Hobot ha-Levavot" of
Bachya. As the author himself had given no name to it, Abraham Bär Flahm, its editor, at first intended to call it "Chovos ha-Levavos he-Chadash" (The New Duties of the Heart, a reference to an 11th Century famous book); but out of respect for the author,
Bachya, he changed his mind. The editor also revised the work, and added to it a preface containing a sketch of Kranz's life, and glosses of his own under the title "Shiyurei ha-Middos". Moses Nissenboim of
Przemyśl extracted from the author's "Ohel Ya'akov" some of the parables, added some of funny stories in the Maggid's name and published them in one book entitled "Mishlei Ya'akov" ("The Parables of Jacob"
Kraków, 1886). Following an open letter by Abraham Flahm printed in the popular
Hagaddah that year claiming plagiarism and forgery, Nissenboim agreed to print Flahm's preface in the succeeding reprints. The agreement is kept to this day. Several parables never published till modern times, but passed on orally in the family, have been written down by Moshe Kranc, a descendant of the Dubner Maggid, in a book about business and Jewish tales: "The Hasidic Masters' Guide to Management". ==Reference Notes==
