Moses married Zipporah (Jethro's daughter) and together they had two sons. The Bible says that Moses became the meekest man on earth ( Numbers 12:3). Working with the sheep day after day taught him both.
God needed to teach Moses patience and trust. Moses spent the next 40 years working as a shepherd for Jethro in Midian. He killed the Egyptian and because of this impulsive act he had to flee from Egypt and from Pharaoh. When Moses was about 40 he saw one of his own people being beaten, and he tried to take things into his own hands. The first 40 years of his life were spent in Egypt, learning first from his mother about God (for 12 years), and then learning from Pharaoh the skills needed to run Egypt. Moses lived to be 120 years old ( Deuteronomy 34:7), but it wasn't until he was 80 years old ( Exodus 7:7) that God called him to lead His people out of Egypt. God is patient and full of love, even though His children are not perfect!) As you read this page please note how much God does to protect His children, who in this case are trusting Him enough to follow His leading, but are still very concerned at times. God's plan of salvation can easily be seen here.
(NOTE: The story of the Exodus is the story of God removing Israel from slavery, but it's also a real-life illustration of God wanting to remove us from the slavery of sin. (Israel Enters Promised Land, Takes Jericho).
