If the previous Pasuk ends the introduction to the Shirah, what is the gist of the remaining five Parshiros until Shevi'i?
Seforno: The rest of the Shirah 1 is divided into five parts 1. Hashem's objective when He created the world and how the early generations failed to achieve it; so Hashem raised Yisrael to the highest levels 2 (until Shelishi). 2. He granted them an ideal location in which to serve Him joyfully, but they rebelled against Him and repaid evil for good, earning themselves a heavy punishment (until Revi'i). 3.
