Dei Rossi appended to some copies of the Me'or Enayim an answer to the criticisms of Moses Provençal, and a dissertation entitled Tzedek Olamim, in which latter he refuted the arguments of Isaac Finzi. Later he wrote a special work entitled Matzref la-Kesef (published by Hirsch Filipowski at Edinburgh, 1854, and included by Zunz in the Vilna edition of the "Me'or"), in which he defended his "Yeme 'Olam" against its critics. Dei Rossi, however, also had to contend with those who considered his "Me'or 'Enayim" as a heretical work.
Dei Rossi engaged with criticisms of the Me'or Enayim, responding to Moses Provençal's objections and composing a dissertation that countered Isaac Finzi's arguments. He also wrote a specialized work, Matzref la-Kesef, which defended his "Yeme 'Olam" against criticism. Dei Rossi faced opposition from those who considered his Me'or Enayim to be unconventional.
