So the whole assembly of those who had returned from the captivity made booths and sat under the booths; for since the days of Joshua the son of Nun until that day the children of Israel had not done so. And there was very great gladness. Also day by day, from the first day until the last day, he read from the Book of the Law of God. And they kept the feast seven days; and on the eighth day there was a sacred assembly, according to the prescribed manner.
