Moreh BeEtzba (“Instructing with a Finger”) addresses proper conduct and customs, including recommendations like not to eat too much at night, to refrain from anger, and to learn Torah immediately after praying. It is part of Avodat HaKodesh (“Work that is Holy”), a compilation of seven short works of law, custom, and ethics written in the late 18th century by Rabbi Chaim Yosef David Azoulai (known as the “Chida” for his acronym). Avodat HaKodesh incorporates talmudic, rabbinic, and kabbalistic teachings, translating them into practical instructions for a proper and holy life. The first Hebrew book to be printed in Jerusalem, it has since been published in more than a hundred editions.
