Parshas Devarim is Moshe Rabeinu's repetition of the story of Jewish people's journey entering Israel. Moshe Rabeinu specifically only speaks to the Jewish people once he has conquered Sichon and Og. Significantly, this parsha is read the week before Tisha B'Av. This parsha is the bridge between Moshe and Yehoshua, the bridge between recognizing Hashem's hand and having to actively be involved. Both sides of the coin are crucial and necessary.
