This class (only) introduces this Sicha: there is a pattern to how Hashem has Moshe visit the Pharaoh. In the first (fourth and seventh) visit(s) He tells him לך… go to the Pharoh at the River. The second (fifth and eighth) visit(s) He tells him בא… Go see him in the palace. The Third (sixth and ninth) visit(s) there is no allusion in the Chumash to what (and how) the warning took place. When He tells him to go to meet him in the palace He says: בא אל פרעה come with Me to the Pharaoh, because Moshe is afraid to go alone.
