'Book of the Law' in the Bible

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

And he read therein before the street that was before the water gate from the morning until midday, before the men and the women, and those that could understand; and the ears of all the people were attentive unto the book of the law.

So they read from the Book of the Law of God, translating and explaining it so that the people understood the reading.

Also day by day, from the first day unto 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 unto the manner.

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