God is always a God of surprises, and He shows up in the most unexpected places and times and to the people least expecting Him.
Moses is no exception. Moses is a fugitive from justice. He escaped Egypt because Pharaoh had heard that he killed an Egyptian. In the land of Midian he met Jethro, who gave him a daughter in marriage. While Moses is working for his father-in-law as a fugitive from justice in a foreign land, God catches up with him.
