Pasuk (33:4):

"The Torah that Moshe commanded us is the heritage of the Congregation of Jacob."

The Torah is an inherited possesion to all of Israel, transmitted from generation to generation.

Rav Mordechai Gifter, in his Sefer Pirkei Torah, asks, that usually the Torah refers to an inheritance by the term of "Nachala" and here the Torah refers to "Morasha", which is a heritage and not an inheritance. 

He explains that a Nachala (inheritance), becomes the complete property of its heirs, and since it is completely theirs, they are able to do with it as they like.  However a Morasha (heritage) is given with "limited ownership", the heirs are only able to use it as stipulated by the original owner.

There are two cases where the Torah writes "a heritage" and not "an inheritance".  Both by the Torah and Eretz Yisroel.  They were both given to us, however we have no right to change any part of it.  We must guard both of these heritages and pass them on in complete form, to our children.

This is obviously a great responsibilty for us, for only if we are careful to keep in tact and preserve the purity of these gifts, will we be able to pass them on to future generations.

Torah is a heritage which all of Clal Yisroel (Kehilat Yakov) are a part of.  We are all part of this heritage, whether we sit and learn the Torah, or we fight the wars for Clal Yisroel, or we work to support the Torah.  

Rav Eliyahu Meir Bloch writes that even though each one may have a different responsibility in life, as long as he helps for a Mitzvah according to his own abilities, he is considered a complete partner in the Mitzvah, like we find by Yissachar and Zevulun.

Rav David Feinstein explains the last Pasuk in this weeks Parsha, Pasuk (34:12): "...and by all the strong hand and awesome power that Moshe performed before the eyes of Israel." 

Every person from the Children of Israel was given the Torah.
Yet every single Jew has a different conception of Hashem, a different way in seeing and understanding Hashem, based on ones education and life experiences.  However, all these various perspectives of Hashem, must lead back to one single source, the Torah which Moshe passed on to us.

Chag Samayach!!!
