In contrast to the convention that there are two successive stages to the Pharaoh’s stubbornness; one where he is stubborn on his own and another where Hashem makes him stubborn, the Rebbe proves that: 1) The two levels of the Pharaoh’s stubbornness are simultaneous and last for the duration of all ten Makkos, beginning with the very first. His first stubbornness makes some sense; while the second makes no sense whatsoever. 2) Moshe was told about these two stubbornnesses so he could combat it with two levels of קבלת עול to counteract Klipa’s stubbornness.
