TSK · Leviticus 23:41

You must not eat bread, roasted grain, or fresh grain until this very day, until you bring the offering of your God. This is a perpetual statute throughout your generations in all the places where you live.

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.
