God has sent me, let the people of Israel go or face his rath
Moses finds a cave and goes in to see what is in the cave
Moses get spoken to by " God " and God tells him that he must save his people and be the savior and protector of " God's people "
God sends Moses to the Pharo to ask for the freedom of " Gods people "
Because the Pharo didn't let the people of Israel go god puts a curse on Egypt to show the Pharo that he is not joking
They call this Passover because god threatened to kill every firstborn son until the Pharo let the people go. God would not have killed your first born son if you killed a lamb and smered the blood over there door. So god would Passover them and not kill their son
