'Law' in the Bible

Only be strong and very courageous, that thou mayest take heed to do according to all the law that Moses my servant commanded thee. Turn not from it to the right or to the left, that thou mayest prosper whithersoever thou goest.

This book of the law shall not depart from thy mouth; and thou shalt meditate upon it day and night, that thou mayest take heed to do according to all that is written therein; for then shalt thou have good success in thy ways, and then shalt thou prosper.

as Moses the servant of Jehovah had commanded the children of Israel, as it is written in the book of the law of Moses, an altar of whole stones, over which iron had not been lifted up. And they offered up burnt-offerings on it to Jehovah, and sacrificed peace-offerings.

And he wrote there on the stones a copy of the law of Moses, which he had written before the children of Israel.

And afterwards he read all the words of the law, the blessing and the curse, according to all that is written in the book of the law.

Only, take great heed to do the commandment and the law, which Moses the servant of Jehovah commanded you, to love Jehovah your God, and to walk in all his ways, and to keep his commandments, and to cleave unto him, and to serve him with all your heart and with all your soul.

And be ye very courageous to keep and to do all that is written in the book of the law of Moses, that ye turn not aside therefrom to the right hand or to the left;

And Joshua wrote these words in the book of the law of God, and took a great stone, and set it up there under the oak that was by the sanctuary of Jehovah.
