The Pentateuch, Torah and Law are the Same

In Hebrew, torah means teaching, instruction or law. So, in English, law is simply a translation of torah. 

Pentateuch is Greek for "five books", and The Pentateuch refers to the same five books of the Bible that are referred to as The Torah or Law by both Jews and Christians.

The most likely author of all five books is none other than Moses, the Lawgiver. 

1. Genesis
2. Exodus
3. Leviticus
4. Numbers
5. Deuteronomy
