Psalm 83:
1 O God, do not remain quiet;
Do not be silent and, O God, do not be still.
2 For behold, Thine enemies make an uproar;
And those who hate Thee have exalted themselves.
3 They make shrewd plans against Thy people,
And conspire together against Thy treasured ones.
4 They have said, "Come and let us wipe them out as a nation,
That the name of Israel be remembered no more."
5 For they have conspired together with one mind;
Against Thee do they make a covenant:
6. The tents of Edom and the Islmaelites;
Moab and the Hagrites;
7 Gebal and Ammon, and Amalek;
Philistia with the inhabitants of Tyre;
8 Assyria also has joined with them;
They have become a help to the children of Lot.
9 Deal with them as with Midian
As with Sisera and Jabin, at the torrent of Kishon,
10 Who were destroyed at En-dor,
Who became as dung for the ground.
11 Make their nobles like O-reb and Zeeb,
And all their princes like Zebah and Zalumunna,
12 Who said, "Let us possess for ourselves
The pastures of God."
13 O my God, make them like the whirling dust;
Like chaff before the wind.
14 Like fire that burns the forest,
And like a flame that sets the mountains on fire,
15 So pursue them with Thy tempest,
And terrify them with Thy storm.
16 Fill their faces with dishonor,
That they may seek Thy name, O Lord.
17 Let them be ashamed and dismayed forever;
And let them be humiliated and perish,
18 That they may know that
Thou alone, whose name is the Lord,
Art Most High over all the earth.
They're now saying it is actually Psalm 84, with the confusion coming from different numbering in the Vulgate from the KJV.

Psalm 83 sounds very up-to-date.
