41 Now while the Pharisees were together, Jesus put a question to them, saying, 42 What is your opinion of the Christ? whose son is he? They say to him, The Son of David. 43 He says to them, How then does David in the Spirit give him the name of Lord, saying, 44 The Lord said to my Lord, Be seated at my right hand, till I put under your feet all those who are against you? 45 If David then gives him the name of Lord, how is he his son? 46 And no one was able to give him an answer, and so great was their fear of him, that from that day no one put any more questions to him.

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.
