JAPHETH BEN DAVID IBN ṢAGHĪR
JAPHETH BEN DAVID IBN ṢAGHĪR (14th century), Karaite scholar and physician in Cairo. Japheth was a pupil of Israel ha-Ma'aravi, and followed his example in rejecting the use of objective analogy (hekkesh) in the rules applying to matrimony and incest. He was the author of Sefer ha-Mitzvot, of which parts 5 to 9 have been preserved in manuscript. In it Japheth quotes many earlier Karaite scholars, including *Daniel b. Moses al-Qūmisī, as well as works of some Rabbanite authors.
