'Law' in the Bible

But Jehu did not take care to walk in the law of the Lord, the God of Israel, with all his heart; he did not turn from the sins of Jeroboam, who made Israel sin.

Then Jehoiada brought out the king’s son and put the crown on him and gave him the Testimony [a copy of the Mosaic Law]; and they made him king and anointed him, and they clapped their hands and said, “Long live the king!”

But he did not put the sons of the murderers to death, in compliance with what is written in the Book of the Law of Moses, in which the Lord commanded, saying, “The fathers shall not be put to death for the sons, nor shall the sons be put to death for the fathers; but each shall be put to death [only] for his own sin.”

Yet the Lord warned Israel and Judah through all His prophets and every seer, saying, “Turn from your evil ways and keep My commandments and My statutes, in accordance with all the Law which I commanded your fathers, and which I sent to you by My servants the prophets.”

Then the king of Assyria commanded, “Take back [to Samaria] one of the priests whom you brought from there, and have him go and live there; and have him teach the people the custom of the god of the land.”

To this day they act in accordance with their former [pagan] customs: they do not [really] fear the Lord, nor do they obey their statutes and ordinances, nor the law, nor the commandments which the Lord commanded the sons (descendants) of Jacob, whom He named Israel;

The statutes and the ordinances and the law and the commandment which He wrote for you [by the hand of Moses], you shall observe and do forever. You shall not fear (worship, serve) other gods.

And I will not make the feet of Israel wander anymore from the land which I gave their fathers, if only they will be careful to act in accordance with everything that I have commanded them, and with all the law that My servant Moses commanded them.”

Hilkiah the high priest said to Shaphan the scribe, “I have found the Book of the Law in the house (temple) of the Lord.” Hilkiah gave the book to Shaphan, and he read it.

Now when the king heard the words of the Book of the Law, he tore his clothes.

Moreover, Josiah removed the mediums and the soothsayers and the teraphim (household gods) and the idols and all the repulsive things that were seen in Judah and in Jerusalem, so that he might fulfill the words of the law written in the book which Hilkiah the priest found in the house (temple) of the Lord.

Before him there was no king like Josiah who turned to the Lord with all his heart and all his soul and all his might, in accordance with all the Law of Moses; nor did anyone like him arise after him.
