They said to Aaron, "Arise and make us a god, because this man, Moses, whom we raised from Egypt, we don't know what he had."
It seems that Moses may have possessed something that he never told the people about. That lack of knowledge caused them to ask Aaron to make a Golden Calf. What was it that Moses possessed, and why did he hide this info from everyone?
