God gave Moses a job to do. God sent him to Pharaoh with a message: “Let my people go.” Pharaoh said no.
Moses told Pharaoh that bad things would happen if Pharaoh wouldn’t let the Israelites go. Still Pharaoh said no.
So God sent six plagues, one after the other – there were locusts, and boils, and frogs. The water in the river turned to blood. The people of Egypt were very frightened. But still Pharaoh said no.
Then God sent one last plague. First, He made His own people safe. Moses told the people of Israel to kill a lamb, and to splash its blood on their doorpost, and to cook the lamb and eat it with unleavened bread and a salad of bitter herbs. They were to eat standing up, with their bags packed ready to travel.
Then God sent the angel of death. The angel visited every house that didn’t have blood on the doorpost, and all the firstborn sons of Egypt died, even Pharaoh’s son.
But Pharaoh was sorry he had let God’s people go. He chased them with his soldiers, all the way to the sea. The people were frightened, but God told Moses to touch the sea with his staff.
Moses obeyed God, and the sea was divided, leaving a dry path for the Israelites to walk through. When they were all on the other side, Moses touched his staff to the sea again, and the water rolled back and drowned the Egyptians who were following.
God’s people were free!
