'Book of the Law' in the Bible

all the people gathered together in the plaza which was in front of the Water Gate. They asked Ezra the scribe to bring the book of the law of Moses which the LORD had commanded Israel.

So he read it before the plaza in front of the Water Gate from dawn till noon before the men and women and those children who could understand. All the people were eager to hear the book of the law.

Ezra read in the book of the law of God day by day, from the first day to the last. They observed the festival for seven days, and on the eighth day they held an assembly as was required.

For one-fourth of the day they stood in their place and read from the book of the law of the LORD their God, and for another fourth they were confessing their sins and worshiping the LORD their God.
