Matthew 22:45

How is he his son? In other words, if David calls Messiah “Lord,” implying that Messiah is older than David himself, how can Messiah also be David’s “Son,” and thus be younger than David? The only possible answer to Jesus’ question is that the One who was to come as Messiah would have existed prior to His incarnation on this earth. As David’s “Lord,” Messiah was none other than the Son of God; as David’s “Son,” Messiah was the Son of man (see on ch. 1:1). Obviously the Jewish leaders were unprepared to answer this question because of their erroneous concepts of the Messiah (see on Luke 4:19). They could not very well answer the question without admitting that Jesus of Nazareth was the Messiah, the Son of God. In asking this question, then, Jesus brought the Pharisees and scribes face to face with the central idea of His mission to earth, for this question would undoubtedly, if faced sincerely and intelligently, have led to the recognition of His Messiahship.
