Deuteronomy 31:9-13

So Moses wrote this law and gave it to the priests, the sons of Levi who carried the ark of the covenant of the LORD, and to all the elders of Israel. Then Moses commanded them, saying, “At the end of every seven years, at the time of the year of remission of debts, at the Feast of Booths, when all Israel comes to appear before the LORD your God at the place which He will choose, you shall read this law in front of all Israel in their hearing. Assemble the people, the men and the women and children and the alien who is in your town, so that they may hear and learn and fear the LORD your God, and be careful to observe all the words of this law. Their children, who have not known, will hear and learn to fear the LORD your God, as long as you live on the land which you are about to cross the Jordan to possess.”
