Sefer Mitzvot Katan (“The Small Book of Commandments,” also referred to by its Hebrew acronym, the Semak) is a 13th-century poetic abridgment of the Sefer Mitzvot Gadol of Moses of Coucy. It blends laws, stories, and ethical teachings, omitting commandments not applicable in the post-Temple era as well as the extensive legal discussions of the Sefer Mitzvot Gadol. The book was originally titled "Sheva Amudei HaGolah" (“The Seven Pillars of the Exile”) because it is divided into seven parts corresponding to the days of the week, in order to encourage daily review. It achieved widespread popularity and was included by some early authorities in the prayer book so that the precepts could be recited daily.
