Yitzchak is about to give Yaakov 10 blessings. These blessings correspond to the 10 utterances that Hashem created the world with. This is a message to us that it is really in the merit of Yaakov and his future descendants (which is us, B’nai Yaakov) that the whole world is continuing to exist. These utterances are alos parallel to the Aseret ha-Dibrot (the 10 commandments), which teaches us that the only way we will merit these 10 blessings is if we uphold the 10 commandments. The 10 commandments include the entire Torah’s 613 mitzvot.
