'Law' in the Bible

Only be strong and very courageous; be careful to do [everything] in accordance with the entire law which Moses My servant commanded you; do not turn from it to the right or to the left, so that you may prosper and be successful wherever you go.

This Book of the Law shall not depart from your mouth, but you shall read [and meditate on] it day and night, so that you may be careful to do [everything] in accordance with all that is written in it; for then you will make your way prosperous, and then you will be successful.

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.

Then afterward Joshua read all the words of the law, the blessing and curse, according to all that is written in the Book of the Law.

Only be very careful and diligently observe the commandment and the law which Moses the servant of the Lord has commanded you to love the Lord your God and walk in all His ways and keep His commandments and hold fast to Him and serve Him with all your heart and with all your soul [your very life].”

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,

And Joshua wrote these words in the Book of the Law of God. Then he took a large stone and set it up there under the oak that was in [the courtyard of] the sanctuary of the Lord.
