Psalm 110

I wonder if David had a vision of the devine conversation that is recorded in this psalm? Did he see some form of the Almighty speaking to a man crowned with many crowns as he received God's promises to rule over all the earth and the appointment to the Melchizedek priesthood? Was David as perplexed about the opening statement in Psalm 110 as the Pharisees where when Jesus quoted them the same phrase? (Matt. 22:41-46) I can only begin to imagine what David experienced that led him to pen this song of royal adoration. It must have made a wonderous impression on the son of Jesse because he recognized two who are greater than he; the LORD of Israel and the other ruler, the one we know to be Jesus.
It only took about 1 minutes to read this psalm.
