Relatively little has been written on Psalm 110 from a biblical-theological perspective. Most modern critical studies go behind the text, concluding that Psalm 110 is essentially a political attempt to unite the Jebusite cult with the Davidic monarchy. Evangelical interpreters take a more theological approach, but rarely develop a satisfying answer to the question of how David would have come to the realisation that the Messiah was to be a priest after the order of Melchizedek.
