In the fifth aliyah Moshe recounts the Jews' travel through certain sections of the desert. These include the land of Seir, which was the land of Yakov avinu's brother Esav's descendants, and the land of Moav, which was the land of Lot's descendants. In each case G-d told the Jews to not fight the people, because the land they are on is theirs to keep as an inheritance. This aliyah ends by recounting the beginnings of the war with Sichon.
