Then the worst plague came upon the Egyptians… Moses told the Israelites to paint lamb's blood on their doors. Then Moses said that if someone had lamb's blood on their door, the angel of death would pass by their house and  death would come upon the first-born of the people without lamb's blood. After the angel of death killed the first born of all Egyptians, the pharaoh let the Israelites go.
       The Israelites left Egypt. A wall of fire formed behind them. The Pharaoh decided to go and get the Israelites back, but his troops couldn't get past the wall of fire. Then the Israelites had to get across the Red Sea. Moses raised his hand and the sea parted. As soon as they got to the other side the sea came back together and drowned the Pharaoh's troops.
