Public Reading

Once every seven years the King of Israel was obligated to read the Book of Deuteronomy to the entire public. 

"Assemble together the people, the men, the women, and the small children so that they will hear, and that they will learn, and fear YHVH, and be careful to fulfill all the words of this Torah."  Deut 31:12

Of all the 613 commandments, this is the only one where small children are explicitly involved, even when they don't understand.  Why was this necessary?  Because the ceremony of the King reading the Torah in public elevated the Torah to such a high level in the children's eyes, that they remained receptive to Torah education as they grew older.
