Jamieson, Fausset and Brown on Luke 20:41

Lu 20:41-47. Christ Baffles the Pharisees by a Question about David and Messiah, and Denounces the Scribes.

41. said, &c.--"What think ye of Christ [the promised and expected Messiah]? Whose son is He [to be]? They say unto Him, The son of David. He saith unto them, How then doth David in spirit [by the Holy Ghost, Mr 12:36] call Him Lord?" (Mt 22:42, 43). The difficulty can only be solved by the higher and lower--the divine and human natures of our Lord (Mt 1:23). Mark the testimony here given to the inspiration of the Old Testament (compare Lu 24:44).
