The Monastery, Petra, Jordan8

Petra is an archaeological site in the Arabah, Ma'an Governorate, Jordan, lying on the slope of Mount Hor in a basin among the mountains which form the eastern flank of Arabah (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. It is renowned for its rock-cut architecture. Petra is also one of the new wonders of the world. The Nabateans constructed it as their capital city around 100 B.C.

Petra is the location where the remnant of Israel fled to through Operation Eagle and stayed during the last 3 1/2 years of Tribulation. It was divinely protected by God during those years that the Israeli and Jewish refugees, as well as members of the Tribulation Force, stayed in Petra, where He fed the people daily with manna and gave them an endless supply of water, created when weapons of mass destruction launched from Amman struck their targets and failed to incinerate them. Tsion Ben-Judah stayed in Petra throughout the last half of the Tribulation to act as the leader and minister of the people, trying to reach out to the undecided refugees with daily teaching of the gospel. However, one group of undecideds rebelled against Tsion and Chaim Rosenzweig and were consumed by the earth swallowing them up, while another group was lured away from Petra by a wonder worker performing various miracles and then were destroyed by fiery serpents.

The town of Petra was put under siege by the Unity Army during the last eighteen months of the Tribulation. The siege ended with the Unity Army storming the walls but finding that their weapons had been made suddenly ineffective, followed by the gruesome annihilation of the attackers by evisceration through Jesus Christ using "the sword of His mouth" immediately following the Glorious Appearing.
