The loyal spokesman[1]
וידבר משה לפני יקוק לאמר הן בני-ישראל לא-שמעו אלי ואיך ישמעני פרעה ואני ערל שפתים: וידבר יקוק אל-משה ואל-אהרן ויצום אל-בני ישראל ואל-פרעה מלך מצרים להוציא את-בני-ישראל מארץ מצרים
Moshe said before Hashem, saying: “Behold! The Jewish people won’t listen to me; how will Pharaoh listen to me? [For] I have blocked lips.” Hashem said to Moshe and to Aharon, and commanded them regarding the Jewish people and to Pharaoh, the king of Egypt, to take out the Jewish people from the land of Egypt[2]
Moshe famously had a speech impediment. He told Hashem that he would have no chance of convincing the Jews of their upcoming freedom, nor Pharaoh that he should let the Jews free. He was of blocked lips. The problem is, Moshe already made this argument in last week’s parsha[3]. When Hashem told Moshe to lead the Jews out of Egypt, he told Hashem that he was heavy of speech. He was unfit for the job. Hashem responded that his brother Aharon would be his spokesman. Moshe would tell Aharon the messages delivered to him from Hashem, and Aharon would tell the people or Pharaoh what was said. Why then is Moshe repeating this argument[4]?
