'Book of the Law' in the Bible

And all the people gathered themselves together as one man into the broad place that was before the water gate. And they spoke to Ezra the scribe to bring the book of the law of Moses, which LORD had commanded to Israel.

Also day by day, from the first day to the last day, he read in the book of the law of God. And they kept the feast seven days, and on the eighth day was a solemn assembly according to the ordinance.

And they stood up in their place, and read in the book of the law of LORD their God a fourth part of the day, and [another] fourth part they confessed, and worshipped LORD their God.
