Moshe was blessed with all the attributes of perfection and purity. He was the paragon of excellence, so that the Jewish people would believe that his superiority was truly a divine gift. Why then was he lacking in his power of speech? Should not this attribute have been included among his special divine gifts? This was also Hashem‘s intention, lest others say that the Jewish people were inspired by Moshe’s rhetoric and style, and moved by his eloquence, rather than by the content of his message. Often, people are emotionally stimulated by rhetoric that covers subtle dishonesties disseminated by the orator. People can be so impressed by the oratory that they are led to believe almost anything to be true. This is the opposite with one who is tongue tied and lacks the self-confidence of a polished speaker. No matter how true and sincere the message, it must be repeated over and over, and scrutinized to be accepted by the people.
