The meaning of Passover originates from the story of God passing over the homes of Isarelites the night he killed
all of the Egyption first born. Who still believes such savagery.
The savage in question was, of course, god.
God had already hammered Egypt with nine plagues, to no effect. For the tenth plague, god told Moses he would kill all the Egyptian first-born sons. God told Moses to have the Israelites daub blood on their front doors, so that god, the killer, would see the sign and would pass over their houses.
Horrible as that is, who here thinks that worse savagery doesn't exist today?
