“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.” Deuteronomy 31:10-13
The Sabbath year in particular was a time that all the people must hear the law.
“Then it will come about that any who are left of all the nations that went against Jerusalem will go up from year to year to worship the King, the Lord of hosts, and to celebrate the Feast of Booths.” Zechariah 14:16
No doubt, the people will hear the law read when they go to the Feast of Booth (Sukkot) in the future. The law was even more read by the king:
“Now it shall come about when he sits on the throne of his kingdom, he shall write for himself a copy of this law on a scroll in the presence of the Levitical priests. It shall be with him and he shall read it all the days of his life, that he may learn to fear the Lord his God, by carefully observing all the words of this law and these statutes, that his heart may not be lifted up above his countrymen and that he may not turn aside from the commandment, to the right or the left, so that he and his sons may continue long in his kingdom in the midst of Israel.” Deuteronomy 17:18-20
