The Problem
Why do the nations rage, And the people plot a vain thing?
The kings of the earth set themselves, And the rulers take counsel together, Against the LORD and against His Anointed, saying,
"Let us break Their bonds in pieces And cast away Their cords from us."

The Response
He who sits in the heavens shall laugh; The LORD shall hold them in derision.
Then He shall speak to them in His wrath, And distress them in His deep displeasure:
"Yet I have set My King On My holy hill of Zion."

The Consequence
"I will declare the decree: The LORD has said to Me, 'You are My Son, Today I have begotten You.
Ask of Me, and I will give You The nations for Your inheritance, And the ends of the earth for Your possession.
You shall break them with a rod of iron; You shall dash them to pieces like a potter's vessel.' "

The Instruction
Now therefore, be wise, O kings; Be instructed, you judges of the earth.
Serve the LORD with fear, And rejoice with trembling.
Kiss the Son, lest He be angry, And you perish in the way, When His wrath is kindled but a little. Blessed are all those who put their trust in Him.

C.H. Spurgeon writes that this Psalm should be called "The Psalm of Messiah the Prince"; for it sets forth as in a wondrous vision the tumult of the people [who are] against the Lord's anointed, the determinate purpose of God to exalt his own Son, and the ultimate reign of that Son over all his enemies. Let us read it with the eye of faith, beholding, as in a glass, the final triumph of our Lord Jesus Christ over all his enemies.
