Psalms 83/18 is an Old Testament prayer of old against terrorists. They were not called terrorists. The words terrorist and terrorism are modern usage, but the blueprints we find in sacred Scripture describe terrorists precisely and provide us as believers in the Word of God, with insider information.
There is more of a Scriptural blueprint collection on terrorists at: http://gospelbillboard.com/TERRORISTS.html on this website.
In the text below, the holy Jewish author makes it immediately clear the targets of the Psalm 83 prayer hate God. They served their evil gods just like modern day terrorists serve the evil gods of this world while they hate the righteous God of Abraham, Isaac and Jacob whom Jewish and Gentile Bible believers in the world serve according to their understanding.
Terrorists have been unified in their purpose by the terrorist State of Iran and Sudan. They are "confederate." They work together even though there are many independent terrorist organizations. They take crafty counsel against America and Israel.
Their purpose is to destroy Israel and Americans whom they refer to as crusaders. By referring to American military intervention in the Middle East as a crusade, terrorist are saying America is there to take control of their religious sites in Mecca and Jerusalem. By labeling American forces as crusaders, terrorists solicit Muslims everywhere to join them in wrecking violence upon Americans and Israeli's in the name of their evil religious book, the Koran.
To pray Psalm 83 in a modern sense, replace the enemies of God then, with those who are the enemies of God, and of Israel and America now.
The Ishmaelites of old are known to us as Arabs today. Edom, Moab, the Hagarenes, Gebal, Ammon, and Amalek are those peoples surrounding Israel geographically today. The Philistines of Goliath the giant, are the Palistinians of Fatah and the Hamas.
Pray specifically against terrorists in all of Arabia, in Iran, Sudan, Pakistan, Afganistan, Egypt, Indonesia and elsewhere in the world.
Pray against the Hamas, Fatah, Hezbollah, al Qaeda, Islamic Jihad, Al-Aqsa Martyrs Brigade, and any other terrorist organization.
Pray against their hiding places, pray against their business and charity fronts, their terrorist cells, their traffic in
bomb building materials and pray their weapons will all be exposed so they can be captured and stopped and removed
from among the living.
