Try "The Old Testament". It explains that the Hebrews had been enslaved by the Egyptians but their God helped them by doing horrible things to Egyptians (especially their children).
Eventually the Hebrews ran away. For some reason only known to their God, Yhwe, He led them all over a desert for forty years until they reached a place they called The Promised Land. It would have only taken them a few weeks to walk there from Egypt had Yhwe actually led them directly. As far as I can tell He did it so He could impress them with tricks like raining food out of the sky.
Then Yhwe demanded that they kill everyone who lived there even though they had done no harm to the Hebrews. I don't know why this was done rather than killing all the Egyptians for what they had done and taking over their land instead.
To this day the Hebrews teach their children that their success in the multiple genocides of the Promised Land is evidence of the glory of Yhwe and their status as the Chosen People. They get really cranky when other people try to live on that land.
This attitude really annoys their neighbours, some who are descended from the tribes they never got around to murdering but only enslaved instead. Unsurprisingly, these people have never trusted the Hebrews and eventually drove them out of the region.
But the Hebrews had a story that one day they would return. For some bizarre reason millions of people who were not Hebrews adopted this same belief. After winning a war they set up a new country shipped the Hewbrews back into the area to fulfill the story they believed in, despite the protests of those who lived there.
The people already living there actually subscribe to an interpretation of the pholosophy by a different guy who had a slightly more enlightened attitute. He allowed people to choose between being massacred or converting to his brand of fascism. But the Hebrews refused to conve
