The Torah tells us that Moshe had a speech impediment. Why did Hashem choose an emissary who was tongue-tied instead of someone who was better suited for the job?
Pharaoh was very stubborn about freeing the Jews from Egyptian bondage. Moreover, Hashem hardened his heart and he became even more reluctant. Due to a series of wonders and miracles designed to demonstrate Hashem’s power, the Jews were enabled to leave Egypt.
If the Jewish leader had been an articulate and eloquent speaker, some people could have erroneously credited Israel’s liberation from Egypt to his power of persuasion. Therefore, Hashem selected Moshe who was not eloquent. His power of speech would never be interpreted as the cause of the redemption of the Jewish people from Egypt, and thus, he was uniquely suited for the role. The intent wasn’t to get the Jews out of Egypt; Hashem didn’t need any help for that.
What He wanted was for the whole world to recognize His mastery over it. For that, it had to be clear that everything came as a result of Hashem’s will and actions, not because Moshe was a gifted leader. As it turns out, there was no one better suited that Moshe, speech impediment and all.
