Deu 5:1 And Moses called all Israel, and said unto them, Hear, O Israel, the statutes and judgments which I speak in your ears this day, that ye may learn them, and keep, and do them.
Deu 6:1 Now these are the commandments, the statutes, and the judgments, which the LORD your God commanded to teach you, that ye might do them in the land whither ye go to possess it:
see a difference?
Yeah I guess there is a difference. So which one is the Law then? Perhaps the first five books are the law together? You could look at the New Testament and perhaps where Jesus answered this man about what commandments to keep.
Matthew 19:16-21:
16 ¶ And, behold, one came and said unto him, Good
Master, what good thing shall I do, that I may have eternal
life?
17 And he said unto him, Why callest thou me good? there
is none good but one, that is, God: but if thou wilt enter into
life, keep the commandments.
18 He saith unto him, Which? Jesus said, Thou shalt do no
murder, Thou shalt not commit adultery, Thou shalt not
steal, Thou shalt not bear false witness,
19 Honour thy father and thy mother: and, Thou shalt love
thy neighbour as thyself.
20 The young man saith unto him, All these things have I
kept from my youth up: what lack I yet?
21 Jesus said unto him, If thou wilt be perfect, go and sell
that thou hast, and give to the poor, and thou shalt have
treasure in heaven: and come and follow me.
So according to Jesus those are the commandments, at least some of them. He didn't list out every single one, but we know where those came from and that they are in the same area as Exodus Chapter 20, or Deuteronomy Chapter 5, etc.
