9 And 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. 10 And Moses commanded them, "At the end of every seven years, at the set time of the year of release, at the feast of booths, 11 when all Israel comes to appear before the Lord your God at the place which he will choose, you shall read this law before all Israel in their hearing. 12 Assemble the people, men, women, and little ones, and the sojourner within your towns, that they may hear and learn to fear the Lord your God, and be careful to do all the words of this law, 13 and that their children, who have not known it, may hear and learn to fear the Lord your God, as long as you live in the land which you are going over the Jordan to possess."

Commentary on Deuteronomy 31:9-13

(Read Deuteronomy 31:9-13)

Though we read the word in private, we must not think it needless to hear it read in public. This solemn reading of the law must be done in the year of release. The year of release was typical of gospel grace, which is called the acceptable year of the Lord; for our pardon and liberty by Christ, engage us to keep his commandments. It must be read to all Israel, men, women, children, and to the strangers. It is the will of God that all people should acquaint themselves with his word. It is a rule to all, therefore should be read to all. Whoever has read of the pains taken by many persons to get scraps of the Scriptures, when a whole copy could not be obtained, or safely possessed, will see how thankful we should be for the thousands of copies amongst us. They will also understand the very different situation in which the Israelites were placed for many ages. But the heart of man is so careless, that all will be found too little, to keep up a knowledge of the truths, precepts, and worship of God.
