Jesus showed that the Messiah must be greater than King David, and not just his descendant.

Matthew 22:41-46

41 While the Pharisees were still gathered together near Jesus, he asked them, 42 “What do you think about the Messiah? Whose descendant is he?” They said to him, “He is the descendant of King David.” 43 Jesus said to them, “If the Messiah is King David’s descendant, then ◄David should not have called him ‘Lord’ when David was saying what the Holy Spirit prompted him to say./Why did David call the Messiah ‘Lord’ when David was speaking what the Holy Spirit prompted him to say?► [RHQ] 44 David wrote this in the Scriptures about the Messiah: ‘God said to my Lord, “Sit here beside me on my right, the place of greatest honor you [MTY]. Sit here while I completely defeat your enemies [MTY].” ’ 45 So, since King David called the Messiah ‘my Lord’, ◄the Messiah cannot be just someone descended from David!/how can he be only the descendant of King David?► [RHQ] He must be much greater than David!” 46 No one who heard what Jesus said was able to think of even one word to say to him in response. And after that, no one else ever dared to ask him another question to try to trap him.
