Psalm 83 appears to be an already-but-not-yet prophecy that may be key to understanding the end times. 

Bill Salus, in his book The Psalm 83 War, wrote that Psalm 83 prophesies a future war in which Israel is attacked by its Muslim neighbors. We think Bill is correct, and further, this war may be used to deceive Jews into welcoming a false messiah—i.e., the Antichrist. 

We also note the hints at a deeper supernatural meaning to the psalm—for example, the neighboring nations are not described as enemies of Israel, but as enemies of God Himself.
