There’s a theme in the old testament that people become nations, e.g. Israel (Jacob) was one of the the sons of Isaac who begat the tribe/nation of Israel. Lot’s daughters who had nonconsensual sex with him while he was unconscious begat Moab and Ammon which went onto create the nations of Moab and Ammon who were neighbors of the ancient Israelites, they were in fairly constant conflict with the Israelites. The story of lot’s rape can be interpreted as a very old and elaborate “your mother fucked her father” joke.
It’s not just the old testament. That’s how those with power tend to think, that their “empire” is a literal physical extension of the self. That’s why Alexander the Great declined to pass his throne down to anyone else, and instead made them all fight to build their own empires.
Gonna call bull on the Alexander part. He died unexpectedly at 32 and no obvious heir or designsted successor. His only legitimate child was still in the womb at the time of his death and his lieutenants recognized their only chance to seize power was to fight for it.
Absolutely was not Alexanders intent for his empire to be ripped apart after his death or he wouldn’t have spent so much time conquering. As far as historians can tell he conquered all he did with the goal of making an empire that could not possibly have a rival strong enough to challenge it. And in those times, people assumed that means they would continue forever, as they had never seen am empire exist long enough in those days to stagnate and implode inward thanks to political infighting.
Similarly, the nation directly south of Moab was Edom.
Edom means red in Hebrew, so the Bible has Edom being founded by Isaac’s oldest son, Esau, who has red hair and sells his birthright to his brother Jacob for a bowl of red lentil stew because he was hungry.
It’s less of a jab than the origin of Moab, but it’s still not super flattering.
