The copy of R. Isaac Izik Grieshaber (1741-1822), rabbi of Paks, author of Makal Noam (Vienna 1799), main polemic against Aaron Hariner and the Reform movement.

R. Moses b. Jacob of Coucy (Count of Coucy) (13th century), French scholar and tosafist. His father Jacob is mentioned a number of times in the printed tosafot (Kid. 43b; et al.). Moses was the maternal grandson of the tosafist R. Hayyim ha-Kohen and brother-in-law of R. Samson of Coucy. His principal teacher was R. Judah Sir Leon.

In 1235 R. Moses traveled in France, and in 1236 in Spain, lecturing publicly in the synagogues on the prescriptions of the Mosaic law and admonishing his audiences to observe them, at the same time, however, emphasizing the truth that mere observance of the oral law to the neglect of justice and brotherly consideration toward others, irrespective of faith or race, can not be counted as meritorious ("SeMaG," Prohibition No. 64; Commandments Nos. 7 and 74). In Spain he found that a number of Jews had married Christians and Mohammedans, and he succeeded in bringing about their divorce (Prohibition No. 112; Commandment No. 3, end). He knew the French, Spanish, and Arabic languages, and was an eloquent speaker; hence he was called "ha-darshan". In 1240, R. Moses was one of the four rabbis who, in a public disputation in Paris, were required to defend the Talmud against the accusations of Donin; R. Jehiel, however, was the only speaker among them. In 1250 R. Moses finished his "Sefer Mitzvot," afterward called "Sefer Mitzvot ha-Gadol" (abbreviated "SeMaG") in order to discriminate it from an extract arranged by R. Isaac of Corbeil and called "Sefer Mitzvot ha-Katon" (abbreviated "SeMaK").
