"The Torah that Moshe commanded us is the heritage of the congregation of Yaakov." (Deuteronomy 33:4)
The Torah was given to us through Moshe, G-d's most faithful servant.
And every single Jew, boy or girl, inherits the torah for himself or herself. Whether they have studied Torah for years, or only know a very little bit, it is their inheritance - to learn and to keep, the very nicest present that G-d gave.
