1 May God arise, may his enemies be scattered;
may his foes flee before him.
2  As smoke is blown away by the wind,
may you blow them away;
as wax melts before the fire,
may the wicked perish before God.
3  But may the righteous be glad
and rejoice before God;
may they be happy and joyful

This Psalm answers the question how does God rescue a nation from the bondage of wicked rulers.The armies of God not only participate in a physical battle but they take action to restore the nation to justice. When we pronounce this Psalm we are asking God to restore the society back to the unity of Gods law. He is praying that God will arise like the ocean waves. The waves of history are like the rolling of the waves. When the waves rise they crash against the ocean floor. In other words render the enemies powerless and drive them from the face of the earth.

But he is not asking to make His people rule but rather give God the praise. Gods people do not control the world through the weapons of man but through Gods axioms. The Psalmist is not forming His prayer according to the way the military plans to win but He speaks the axioms and everything is done by God. When the righteous are united in praising God then the nation is restored.God not only fights for us but He restores us by the praise we give Him. 

Sing to God, sing praise to his name,
extol him who rides on the clouds  -
his name is the LORD -
and rejoice before him.
We go forth speaking the law, covenants, curses, statutes ,promises, and decrees. We speak the law and God arises. The curses and our enemies are removed. The promises and we are united , the statues and we are safe in the pillars of Gods law, the decrees and God rules in the pronouncements. We are Gods army cheering Him on.

 A father to the fatherless, a defender of widows,
is God in his holy dwelling.
God sets the lonely in families, 
he leads forth the prisoners with singing;
but the rebellious live in a sun-scorched land.
The axioms are prayers to reverse the destruction. The wicked abuse within the nation. We are the army of God who is there to help the abused. We rule  the world by pronouncements. We are not here to restore our own fortunes but to see God restore the people through redemption.

 When you went out before your people, O God,
when you marched through the wasteland,
Selah
the earth shook,
the heavens poured down rain,
before God, the One of Sinai,
before God, the God of Israel.
You gave abundant showers, O God;
you refreshed your weary inheritance.
Your people settled in it,
and from your bounty, O God, you provided for the poor.

God simply speaks and the enemies flee. So God fights by restoring the nation. He returns the money  that is taken from His people from the wayward leaders. He refreshes His people. When God fights He restores His people. So we speak the axioms and we are united and refreshed.

 The Lord announced the word,
and great was the company of those who proclaimed it:
 "Kings and armies flee in haste;
in the camps men divide the plunder.
Even while you sleep among the campfires,
the wings of my dove are sheathed with silver,
its feathers with shining gold."
 When the Almighty scattered the kings in the land,
it was like snow fallen on Zalmon.

When we speak the pronouncements we understand that God only needs to speak a word and the war is ended.  God does the fighting and we live in perfect unity.

 The mountains of Bashan are majestic mountains;
rugged are the mountains of Bashan.
Why gaze in envy, O rugged mountains,
at the mountain where God chooses to reign,
where the LORD himself will dwell forever?
 The chariots of God are tens of thousands
and thousands of thousands;
the Lord has come from Sinai into his sanctuary.
When you ascended on high,
you led captives in your train;
you received gifts from men,
even from the rebellious-
that you, O LORD God, might dwell there.

The Psalmist is saying that God  fights the wars then sets up His presence on the Temple mount. If God is present then Israel is safe and united. The axioms focus on uniting Israel as God is present in the Temple.
Praise be to the Lord, to God our Savior,
who daily bears our burdens.
Selah
 Our God is a God who saves;
from the Sovereign LORD comes escape from death. Most of the Psalms end in a prayer for God to unite Israel. God is not a God of war but a God who saves. We cannot win by our own weapons. We win when we give God  the glory for saving the world. We are pessimistic by nature but God is always optimistic.  Pessimism is spread because we do not give God the authority to curse the wicked but we make God pragmatic.
Surely God will crush the heads of his enemies,
the hairy crowns of those who go on in their sins.
The Lord says, "I will bring them from Bashan;
I will bring them from the depths of the sea,
 that you may plunge your feet in the blood of your foes,
while the tongues of your dogs have their share."When we must fight with God on our side it is total destruction of the enemy.
Your procession has come into view, O God,
the procession of my God and King into the sanctuary.
In front are the singers, after them the musicians;
with them are the maidens playing tambourines.
Praise God in the great congregation;
praise the LORD in the assembly of Israel.
There is the little tribe of Benjamin, leading them,
there the great throng of Judah's princes,
and there the princes of Zebulun and of Naphtali.
When Gods procession goes to war the muscians are leading in the axioms and  the armies are not strong. God does not need man to win wars. He wants to be praised.
  Summon your power, O God;
show us your strength, O God, as you have done before.
Because of your temple at Jerusalem
kings will bring you gifts.
 Rebuke the beast among the reeds,
the herd of bulls among the calves of the nations.
Humbled, may it bring bars of silver.
Scatter the nations who delight in war.
  Envoys will come from Egypt;
Cush will submit herself to God.
The axioms create more victories than real wars. When God shows His power He simply causes the nations to be friendly and the nations to bring his people gifts. The axioms create the submission of the world.
  Sing to God, O kingdoms of the earth,
sing praise to the Lord,
Selah
to him who rides the ancient skies above,
who thunders with mighty voice.
Proclaim the power of God,
whose majesty is over Israel,
whose power is in the skies.
You are awesome, O God, in your sanctuary;
the God of Israel gives power and strength to his people.The axioms cause all the people of the world to give God the glory for His power .
