He apparently raised his younger brother David following the death of their father, and was a major influence in his commentaries.[4]
Career as a commentator
Like his father, he wrote a number of commentaries on the Bible, basing himself on the literal meaning of the text. His surviving works include commentaries on the books of Proverbs, Job,[5]Ezra, and Nehemiah.[6]
He also wrote a book of essays on Hebrew grammar,[7][8] known, after the first three words, as Mahalak Shebile Ha-daat, or briefly as Mahalak. In it he described the underlying principles of his commentaries, combined with tangential discussions of medieval philosophy. This handbook was of great historical importance
as in the first half of the 16th century it became the favourite manual for the study of Hebrew among non-Judaic scholars.[9]
