The Law, also known as the Torah, the five books of Moses, or Ten Commandments, is the main part of the Jew Testament. Although it is action-packed, it is generally not considered as good as the New Testament, because it doesn't mention The Baby Jesus at all. This is probably because it was written by Jews, who don't believe in The Baby Jesus and will thus burn in the Lake of Fire. Christians read this book for the same reason people went to see Episodes 1-3 of Star Wars - it wasn't as good as the later part of the story, but it was made by the same person (God or George Lucas).
