Deuteronomy 31:9-13

9And Moses wrote this law, and delivered it unto the priests the sons of Levi, that bare the ark of the covenant of Jehovah, and unto all the elders of Israel. 10And Moses commanded them, saying, At the end of every seven years, in the set time of the year of release, in the feast of tabernacles, 11when all Israel is come to appear before Jehovah thy God in the place which he shall choose, thou shalt read this law before all Israel in their hearing. 12Assemble the people, the men and the women and the little ones, and thy sojourner that is within thy gates, that they may hear, and that they may learn, and fear Jehovah your God, and observe to do all the words of this law; 13and that their children, who have not known, may hear, and learn to fear Jehovah your God, as long as ye live in the land whither ye go over the Jordan to possess it.
