'Law of Moses' in the Bible

just as Moses the servant of the Lord had commanded the sons of Israel, as it is written in the Book of the Law of Moses, an altar of uncut stones on which no one has wielded an iron tool; and they offered on it burnt offerings to the Lord, and sacrificed peace offerings.

And there, in the presence of the sons of Israel, Joshua wrote on the stones a copy of the Law of Moses which Moses had written.

Be steadfast and very determined to keep and to do everything that is written in the Book of the Law of Moses, so that you do not turn aside from it to the right or the left,
