“The kings of 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” (Psalm 2:2-3).
Having been written in response to a rhetorical question about corruption, this passage describes attitudes, behaviors, and decisions of rulers who show their disdain or at least disregard for the existence of a Higher Power
The description of kings and rulers in the psalm might lead one to believe it was written in reference to certain kings who, in rebellion, set themselves up against the Almighty; however, scholars are unable to pinpoint exactly which kings and which period of time might be referred to—so, the principle can apply to any time.
The powerful of the earth feel secure as they set themselves up and rule their kingdoms in derision of both God and His Anointed Son, thinking their power makes them accountable to no one.
Even today so many leaders of nations appear to oppose all things spiritual as they make laws that affect the lives of their constituents. God is great, just, and holy and, therefore, to be feared. The rulers of the earth have evidently not figured that out, according to the psalmist. Rather than oppose Him, they should reverence Him and stand in awe of Him, submitting to Him with fear and trembling.
