Is the Christ David's Son?

Mark 12:35-37

As Yeshua was teaching in the Temple, he asked, "How is it that the Torah teachers say the Messiah is the Son of David?

David himself, inspired by the Ruach HaKodesh, said, `ADONAI said to my Lord, "Sit here at my right hand until I put your enemies under your feet." '

David himself calls him `Lord'; so how is he his son?" The great crowd listened eagerly to him.
