Комментарий к Шмот 9:13

השכם בבוקר, "rise up early in the morning, etc!" Moses was given three separate instructions here. 1) To go to see Pharaoh early in the morning. 2) To adopt an erect posture when facing Pharaoh, not to bow down as was customary.

Moses was not do discard his natural humble stance except in the presence of Pharaoh. 3) He was to communicate G'd's message to Pharaoh.
