thorah

Though these were the ordinary Hebrew titles of the successive Pentateuchal books, certain Rabbinic writers denote the last three according to their contents; they called the third book torath kohanim, or law of priests; the fourth, homesh happiqqudhim, or book of census; the fifth, mishneh thorah, or repetition of the law.
