“Nowe Moses kept the flocke of Iethro his father in law, the Priest of Midian: and hee led the flocke to the backeside of the desert, and came to the mountaine of God, euen to Horeb.”
1611 King James Version (KJV)
3:1 Now Moses - The years of Moses's life are remarkably divided into three forties; the first forty he spent as a prince in Pharaoh's court, the second a shepherd in Midian, the third a king in Jeshurun. He had now finished his second forty when he received his commission to bring Israel out of Egypt. Sometimes it is long before God calls his servants out to that work which of old he designed them for. Moses was born to be Israel's deliverer, and yet not a word is said of it to him till he is eighty years of age. Even to Horeb - Horeb and Sinai were two tops of the same mountain.
