Augustine of Hippo
Moses appears to express his inability to speak effectively with his words, "Behold, I am speechless: how shall Pharaoh hear me?" He highlights the frailty of his voice, which was inadequate not only to reach a multitude but even a single individual. It's remarkable that his silence rendered him unheard by anyone. Perhaps the pride of royalty obstructed them from engaging directly? Nonetheless, it is declared to him, "See, I have set you as God to Pharaoh, and Aaron your brother shall be your prophet" (Exodus 7:1).
