The Pharaoh remains stubborn despite the Nine Plagues and Moses' pleadings to free the Israelites. Finally, the Pharaoh agrees to let the Israelites go after many first born sons were killed (including his) by the Angel of Death, the Tenth and Final Plague. Again, Israel is safe from the Angel of Death because they obeyed God's instructions through Moses. The episode also includes the parting of the Red Sea when the Pharaoh and his chariots chased the Israelites after changing his mind.
