Chp. 28 verses 1 - 47: Moshe tells the people all the blessings they will receive if they keep G-d's Torah. Then he enumerates all the curses that will befall them if they rebel against Hashem and His Torah. All their difficulties will occur because " You did not serve the L-rd your G-d with joyfulness and with gladness of heart, by reason of the abundance of all things."
