Law of Moses
The Law of Moses refers primarily to the Torah or first five books of the Hebrew Bible, traditionally believed to be written by Moses.
Terminology
The Law of Moses or Torah of Moses (Hebrew Torat Moshe תֹּורַת מֹשֶׁה, Septuagint Greek nomos Moyse νόμος Μωυσῆ) is a biblical term first found in the Book of Joshua 8:31-32 where Joshua writes the Hebrew words of "Torat Moshe תֹּורַת מֹשֶׁה" (translated as "Law of Moses", meaning "instructions of Moses") on the altar at Mount Ebal. The text continues "And afterward he read all the words of the teachings, the blessings and cursings, according to all that is written in the book of the Torah." (Joshua 8:34). The term occurs 15 times in the Hebrew Bible, another 7 times in the New Testament, and repeatedly in Second Temple period, intertestamental, rabbinical and patristic literature.
The usage of the Hebrew term Torah (which was translated into Greek as "nomos" or "Law") as equivalent to the English term "Pentateuch" (from Latinised Greek), meaning the "Five Books of Moses" of the Hebrew Bible, is clearly documented only from the 2nd Century BCE. In modern Hebrew the term Torah (typically translated into English as "instruction") refers to both the first section of the Tanakh and to the "Torah of Moses" itself, the actual regulations and commandments found among the 2nd to 5th books of the Hebrew Bible. Rarely in English "the Law" can also refer to the whole Pentateuch including Genesis, but this is generally in relation to New Testament uses where nomos "the Law" sometimes refers to all five books, including Genesis. This use of the Hebrew term "Torah, 'Law'," for the first five books is considered misleading by bible scholar John Van Seters since the Pentateuch "consists of about one half law and the other half narrative." The adjective "Mosaic" meaning "of Moses" is also found in the description "Mosaic Law" in which case only the actual law, not the five books is intended.
