Kad ha-Kemah consists of sixty chapters, alphabetically arranged (alphabet in not maintained witin the letter), containing discourses and dissertations on the requirements of religion and morality, as well as Jewish ritual practices. Its purpose is to promote a moral life. In it R. Bahya discusses the following subjects: belief and faith in G-d; the divine attributes and the nature of providence; the duty of loving G-d, and of walking before G-d in simplicity and humility of heart; the fear of G-d; Jewish prayer; benevolence, and the love of mankind; peace; the administration of justice, and the sacredness of the oath; the duty of respecting the property and honor of one's fellow man; the Jewish holidays, and halakha (loosely translated as "Jewish law".)

R. Bahya b. Asher b. Hlava (13th century), exegete, preacher, and kabbalist. His great commentary on the Pentateuch (Naples, 1492) was written in 1291. According to tradition, he lived in Saragossa and served there as dayyan and preacher. He was a disciple of R. Solomon b. Abraham Adret, whom he called "my master," whenever he quoted from his commentaries. Curiously enough, R. Bahya mentions neither his teacher's kabbalistic sayings nor his commentaries on the mystical teachings of Nahmanides as did R. Solomon b. Adret's other disciples. There are also kabbalistic matters quoted anonymously by Bahya which are attributed to R. Solomon b. Adret by other authors.
