Psalm 83 describes the beginning and reasoning for the war (that the name of Israel may be remembered no longer) but it does not really describe the final state of the Arab countries that attack Israel (not all Arab countries do). A possible description can be found in Isa 17, Jer 48 and Eze 25 and 37. Most important, Psalm 83 involves only those Arab countries that immediately surround Israel.
Which Arab countries don’t border Israel?
Syria, Lebanon, Jordan, Saudi, and Egypt do.
