God's people, the Israelites, were slaves in Egypt for 400 years. God chose Moses to lead the Israelites out of Egypt to their own land where they could worship freely. Moses and his brother Aaron went to Pharaoh and demanded "Let my people go!" but Pharaoh refused. God sent 10 plagues upon Egypt to convince Pharaoh - water turned to blood, frogs, gnats, flies, livestock died, boils, hail, locusts, darkness, and the death of the firstborn. After the final plague, Pharaoh finally let the Israelites go. God demonstrated his power over the gods of Egypt and showed his love for his people.
