פרשת ויגש - PARSHAS VAYIGASH
"And do not be angry with your servant, because you are like Pharaoh" - "ואל יחר אפך בעבדך כי כמוך כפרעה"
The concept taught by this is that when the Tzaddik of a generation goes to pray for the Jewish people, and to bring down the blessings of all goodness upon them, the first thing he does is to defend them on the account of failing to follow the proper path until now. He shows God the greatness of the fire of the evil urge that burns in a person's heart constantly to the point where it darkens the vision of a Jewish person's intelligence on such a level to where he cannot sense nor discern the difference between serving God and the urges of the evil inclination, God forbid. This defense that the Tzaddik defends us with before God is "and do not be angry with Your servant", for it is not proper nor fair to be angry with us, God forbid, because the evil urge has tricked us to the extent that "You are like Pharaoh", and we cannot discern between You and between the concept of the power of the evil urge, which is symbolized by Pharaoh.
