The meaning of Susya is, exalt Yahuah. This we know was not what happened because of the Greek Zodiac on the floor of the government/temple building.
The people around Susya was Edomites, a nomadic people of the arid wilderness. The Jews of Susya would hide there food in caves to protect it from the Edomites. What is interesting is that Edomites was a foundation of Rome.
Susya became forgotten. It's not mentioned in history or by Christians. It's not known what happened to the Jews that lived there. We do know it was Jewish because the cemetery is the distance dictated from the city by the Talmud. When Islam was created, Muslims took over Susya and converted the city into a Muslim government/religion. After this, the sand took it over and was forgotten.
What is to be learned here? The gods of the Zodiac could not protect Susya. The Talmud could not protect Susya. The riches of the wealthy could not protect Susya. It was abandoned until the Jews came back to it, making Susya a historical site. Susya is still a war between Jews, Muslims and Christians. This time it's the interpretation of History.
As for me, Susya is interesting because it was forgotten. Jews could not protect Jerusalem from the Romans, but killed and cast out Christians, a people who would not have destroyed Jerusalem. It's this thinking that probably ended Jewish Susya. The Christians near Susya probably took refuge in Egypt creating a vacuum for more Edomites that once was somewhat pushed back.
