The Artscroll Chumash
The Torah is the compilation of the first five books of the Hebrew Bible, namely the books of Genesis, Exodus, Leviticus, Numbers and Deuteronomy. The Torah is known as the Pentateuch or the Five Books of Moses by Christians. It is also known as the Written Torah in Rabbinical Jewish tradition. If meant for liturgic purposes, it takes the form of a Torah scroll. If in bound book form, it is called Chumash, and is usually printed with the rabbinic commentaries.
