41 As the Pharisees were regrouping, Jesus caught them off balance with his own test question: 42 "What do you think about the Christ? Whose son is he?" They said, "David's son." 43 Jesus replied, "Well, if the Christ is David's son, how do you explain that David, under inspiration, named Christ his 'Master'? 44 God said to my Master, "Sit here at my right hand until I make your enemies your footstool." 45 "Now if David calls him 'Master,' how can he at the same time be his son?" 46 That stumped them, literalists that they were. Unwilling to risk losing face again in one of these public verbal exchanges, they quit asking questions for good.

Commentary on Matthew 22:41-46
(Read Matthew 22:41-46)
When Christ baffled his enemies, he asked what thoughts they had of the promised Messiah? How he could be the Son of David and yet his Lord? He quotes Psalm 110:1. If the Christ was to be a mere man, who would not exist till many ages after David's death, how could his forefather call him Lord? The Pharisees could not answer it. Nor can any solve the difficulty except he allows the Messiah to be the Son of God, and David's Lord equally with the Father. He took upon him human nature, and so became God manifested in the flesh; in this sense he is the Son of man and the Son of David. It behoves us above all things seriously to inquire, "What think we of Christ?" Is he altogether glorious in our eyes, and precious to our hearts? May Christ be our joy, our confidence, our all. May we daily be made more like to him, and more devoted to his service.
