Experience of the one being able to leave the cave ; found God
When Moses was a baby, it was during a time when the Pharaoh of Egypt was killing boy babies to reduce the population of the Israelites. Moses was saved when his birth mother put him in the river, hoping someone will find him. it was the Priceess of Egpyt who later found him and adoted him
Pharaoh didn't like that Moses brought a "new God" to the land stated that He was a false God.
Experience of the one upon returning to the cave
The Israelites are slaves used to build the stautes (shadows; the stautes of the Pharaoh were considered God of the land) and plant food for the Royality.
When training, Moses killed a Pharaoh slavemaster. He had to go away (outside of the cave) because killing a slavemaster is punishable by death. He was not to ever return home. One night while walking on Mount Horeb, a brush was burning and the Angel of the Lord spoke to him telling him to "Set my people free"
Moses dying never getting able to see the Promised Land
Moses then went back to convine the Pharaoh to let the Isrealites go. He didn't and each day he resisted, the 10 plauges progressed. The pharaoh's son was one of the casualties of the plaugues and the Pharaoh ended up setting them free
Moses then led them to the red sea, where God enabled him to split the Red Sea, in order for the Isrealites to cross. Drowning any Egyptian who dare follow.
