The Torah portion is a song, a poem taught to the Jewish people by Moshe. It recounts the trials and tribulations of the Jewish people during the 40 years in the desert. Jewish consciousness, until the present generation, was to teach every Jewish child to memorize Ha’azinu. In this manner we internalized the lessons of our history, especially the futility of rebelling against the Almighty.
The portion ends with Moshe being told to ascend Mount Nevo to see the Promised Land before he dies and is “gathered to his people”. By the way, this is one of the allusions to an afterlife in the Torah. Moshe died alone and no one knows where he is buried. Therefore, “gathered to his people” has a higher meaning!
