ISAAC NATHAN BEN KALONYMOS

The author prepared this work to assist Jews engaged in polemical debate with Christians. The text is ordered according to the roots and stems of the words. The second work was prepared as an addendum to the Meir Nathiv as announced in the publishers' foreword. However, as Prijs notes, the printing took longer than expected and so the Toldoth Aaron was issued in Freiburg two years later. See Ziphroni’s interesting, cryptic colophon on the final leaf of the Toldoth Aaron. “I will announce in the future the reason for the delay in printing: Two Jews (one residing in Prague and one in Poland) should be ashamed and disgraced for causing our failure, may God pay them back for their actions” These two works are often bound as a single unit, to enable scholars to have the convenience of studying a concordance and index to Biblical verses in the Talmud in a single volume
