This highlights a twofold relationship: David’s Son and David’s Lord. The Messiah, who is both the Son of David and the Lord of David, transcends ordinary human lineage. This paradox underscores the divine nature of the Messiah and His unique role in salvation history. This part of Luke 20>, when David calls the Messiah “my Lord,” points to a profound truth, that the Messiah is not just an earthly heir but also the eternal Lord. 


Luke 20:41-44 Easy English Bible> Jesus said to them, ‘Why do people say that the Messiah will be King David’s son? David himself said this in the book called Psalms: “The Lord God said to my Lord, Sit at my right side until I win against your enemies. Then you will be able to put your feet on them.” You see here that David calls the Messiah his Lord. So can you really say that the Messiah is David’s son?’
