Moshe describes the desolation of the Land of Israel which will be a result of the failure to heed Hashem's mitzvos. Both their descendants and foreigners alike will remark on the singular desolation of the Land and its apparent inability to be sown or to produce crops. Moshe promises, however, that the people will eventually repent after both the blessings and the curses have been fulfilled. However assimilated they will have become among the nations, eventually Hashem will bring them back to Eretz Yisrael. The Parsha concludes with a dramatic choice between life and death.
Moshe exhorts the people to choose life.
Moshe tells them that whether he is among them or not, Hashem is with them, and will vanquish their enemies. Then he summons Yehoshua, and in front of all the people, exhorts him to be strong and courageous as the leader of the Jewish People. In this manner, he strengthens Yehoshua's status as the new leader. The sections that he reads deal with faithfulness to Hashem, the covenant, and reward and punishment. Hashem tells Moshe that his end is near, and he should therefore summon Yehoshua to stand with him in the Mishkan, where Hashem will teach Yehoshua.
