This work contains his commentaries on seven different treatises of the Babylonian Talmud. A second edition of this work was published in Berlin in 1756. His Talmudic commentaries are now known as Hiddushei HaRashba.

He served as rabbi of the main Synagogue of Barcelona for 50 years, and as a Rabbinical authority his fame was such that he became known as 'The Rabbi of Spain'. Moses ben Nahman (Nahmanides) and Jonah of Gerona were his teachers. HaRashba was a master in the study of the Talmud, he also accepted the Kabbalah. Many other of his works appeared in print, starting in the 16th century, among them his famous Responsa works.
