Matthew 22:41-45

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?"
