Sefer ha-galui

The Sefer ha-galui is a work by Joseph Kimhi, a European grammarian and biblical exegete who lived in the 12th century. This book, meaning "Book of the Demonstration," focused on lexicography and exegesis. In it, Kimhi criticized the work of Jacob ben Meir Tam, a prominent Talmudic scholar of his time.1

Joseph Kimhi, along with his sons Moses and David, significantly contributed to Hebrew language studies. David Kimhi, Joseph's son, later became a renowned scholar of the Hebrew language, whose works on grammar and lexicography became standard texts in the Middle Ages. His major work, the Sefer mikhlol, was intended to include both a grammar and a lexicon, with the lexicon appearing separately as the Sefer ha-shorashim.12
