Psalm 2 is a conversation amongst the Trinity regarding the futile efforts of wicked men to dethrone God.  This is referring to the Antichrist and his forces that are squashed in the end (literally, according to Isaiah 63:1-6).  In the end, the Lord will have His Anointed to rule the universe.  Who is God’s Anointed?

-Moses-

-Elijah-
