May God Bless You … & this is my final question. What was Moses doing during those 40 years he was (so-to-speak, on the back side of the mountain) away from his people and Egypt … before he finally emerged and went back to Egypt to confront Pharaoh?
During these forty years there not much is recorded of what Moses did, and all we know is that he shepherded the flock of his father-in-law.
The Sages write that tending to the sheep was a preparation for leading the nation of Israel in later times: Somebody who is able to care for sheep, and learns to tend to all their needs, will also be able be a worthy leader of the nation.
Best wishes, and please ask whatever questions you wish!
