Rabbi Chizkiyahu ben Rabbi Manoach

Rabbi Chizkiyahu ben Rabbi Manoach (13th century) known as the Chizkuni was a French rabbi and student. In memory of his father, who lost his right hand through his stead-fastness in the faith, Rabbi Chizkiyahu wrote (in about 1240) a commentary on the Pentateuch, under the title Chizkuni. It was printed at Venice in 1524. Other editions appeared at Cremona (1559), at Amsterdam (1724, in the Rabbinical Bible of M. Frankfurter), at Lemberg (1859), etc. It is based principally upon Rashi, but it uses also about twenty other commentaries, though the author quotes as his sources only Rashi, Dunash ben Labrat, the "Yosippon", and a "Physica" which is mentioned in the Tosafot (to Lev. xii. 2). He is generally cited by the title of his commentary.
