When humans do insane transactions they are finally grabbing at some quality of Ggodliness, belonging to Heaven -- the oil that greases the soon-to-be-squeaky wheels of the chariot, for instance -- and seizing them for their own gain.
Esau had his twelve tribes, stayed near his father's house, and was a mighty warrior. Meanwhile, Jacob was not allowed to keep the name his mamma gave him -- when blessed -- he needed big protection to face being near his brother again and he toiled years for his father in law. In other words, Esau knew what he was doing. Heaven blessed him big-time. That does not mean Esau made the LORD happy.
This is why the LORD's people, in the days of yore, had an ark they grew frightened of, miracles they hated, a God they rejected, and were defined as a people to support warfare in all they did. Jacob knew not to war with his brother. Esau's Ggods were not the Ggods he wanted. When the Ten Commandments were written humans were required to avoid doing the works that meant Heaven was killing fellow Spirit. Other commandments were likewise. Cain2 was protected as a murderer to symbolise God putting a stop on all Spirit being destroyed by humans deeds to destroy fellow Spirit. Obviously the warring nation of Israel were killing and "somehow" they got to kill some more. Cain killing Abel preserved Sprit sons, not humans. When people choose warfare as a profession the problems of Valley Forge, that General George Washington faced, are handmaidens of warfare on all the other Ggods of the world ticket. The LORD built his warfare protocols off Allness' enforcer. mac backs all the LORD did protecting Him as Firstborn no different than God, in Genesis, protecting Cain. No, mac isn't stating for a certainty where the LORD's tattoo is. But Jehovah's is on his dick. All that was done to the LORD by this nation, America, is what Jehovah the god is.
Once Cain killed Abel the direction of humanities interaction with the Ggods needed to include no killing. This needed to be fulfilled across Spirit. Flesh by its very nature is disposable, duh. People can even kill themselves and no God stops them.
