Like many psalms, the theme of Psalm two is emphasize in the final verse. We can defy God and Perish, Or we can surrender to him and be blessed.
In Psalm 2:1-3. The nations rebel. The nations speaking
Why did the nations rage and all the people plot a vain thing? The kings of the Earth, except themselves, and the rulers of the nation state Council together, against the Lord, and against his anointed one saying Let us break their bonds in peace’s and cast away their cords from us.
In Psalm 2:4-6. God laughs. God speaking
He who sits in the heavens, shall laugh; The Lord to hold them in derision. Then he will speak to them and His wrath, And distress them in His deep displeasure: Yet I have sent My King on My holy My in Zion.
In Psalm 2:7-9 . The decree of the Son. Jesus speaking.
I will declare and decree: The Lord has said to me, You are My Son, today I have begotten You. Ask of Me, and I will give to the nations for Your Inheritance, And the ends of the Earth for Your possession. You will break them like a rod of iron; you shall dash them into pieces like a potters vessel.
In Psalm 2:10-12. Be instructed. The Holy Spirit speaking.
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 those who put their trust in Him.
