The Tanakh consists of twenty-four books: it counts as one book each Samuel, Kings, Chronicles and Ezra–Nehemiah and counts Trei Asar (תרי עשר, the Twelve Prophets; literally "twelve") as a single book.
The Torah (תּוֹרָה, literally "teaching") consists of five books, commonly referred to as the "Five Books of Moses". Printed versions of the Torah are often called Chamisha Chumshei Torah (חמישה חומשי תורה, literally the "five fifth-sections of the Torah"), and informally a Chumash.
In Hebrew, the five books of the Torah are identified by the first prominent word in each book.
