'Book of the Law' in the Bible

And they taught in Judah, and had the book of the law of Jehovah with them; and they went about through all the cities of Judah, and taught among the people.

And when they brought out the money that had been brought into the house of Jehovah, Hilkijah the priest found the book of the law of Jehovah by Moses.

Then Hilkijah spoke and said to Shaphan the scribe, I have found the book of the law in the house of Jehovah. And Hilkijah gave the book to Shaphan.
