The death of the firstborn finally breaks Pharaoh's resistance and he literally begs the Children of Israel to leave his land. Following G-d's command, they hastily depart; so hastily that there is no time for their dough to rise, and the only provisions they take along are unleavened. Before they go, they ask their Egyptian neighbors for gold, silver and garments, emerging from Egypt a wealthy nation.
The Children of Israel are commanded to observe the anniversary of the Exodus each year by removing all leaven from their possession for seven days, eating matzah, and telling the story of their redemption to their children.
Soon after allowing the Children of Israel to depart from Egypt, Pharaoh chases after them to force their return, and the Israelites find themselves trapped between Pharaoh's armies and the sea. G-d tells Moses to raise his staff over the water; the sea splits to allow the Israelites to pass through, and then closes over the pursuing Egyptians. Moses and the Children of Israel sing a song of praise and gratitude to G-d.
