The Rebbe connects the theme of Hakhel to the Mitzvah of the Bris Milah which is found at the end of Parshas Lech Lecha.
The Bris Milah is a covenant between Hashem and the Jewish people. It is a general covenant that connects us to Hashem and binds us to Torah and Mitzvos in an eternal bond. The Bris also unites and connects all Jews to one another.
These are the same themes reflected in Hakhel; the unity of the Jewish people and the strengthening of the covenant (Bris) between Hashem and the Jewish people and our observance of the Mitzvos.
