Is the Christ David's Son?

Mark 12:35-37

While Jesus was teaching in the temple courts, He asked, “How can the scribes say that the Christ is the Son of David?

Speaking by the Holy Spirit, David himself declared: ‘The Lord said to my Lord, “Sit at My right hand until I put Your enemies under Your feet.”’

David himself calls Him ‘Lord.’ So how can He be David’s son?” And the large crowd listened to Him with delight.
