"Sefer ha-Ḥibbur" () is Berechiah's best-known philosophical work, wherein he develops on the works of Saadia Gaon, Bahya ibn Pakuda, and Solomon ibn Gabirol. Berechiah was also the author of an ethical treatise entitled "Sefer Matzref", divided into thirteen chapters. In it he quotes Rabbi Abraham ibn Daud (died c. 1198) without the formula for the dead, so that it is quite probable that the book was composed before 1180. In these essays he invented several Hebrew terms for philosophical concepts.
