41 Then Jesus presented them with a question. "Why is it," he asked, "that the Messiah is said to be the son of David? 42 For David himself wrote in the book of Psalms: 'The Lord said to my Lord, Sit in the place of honor at my right hand 43 until I humble your enemies, making them a footstool under your feet.' 44 Since David called the Messiah 'Lord,' how can the Messiah be his son?"
45 Then, with the crowds listening, he turned to his disciples and said, 46 "Beware of these teachers of religious law! For they like to parade around in flowing robes and love to receive respectful greetings as they walk in the marketplaces. And how they love the seats of honor in the synagogues and the head table at banquets. 47 Yet they shamelessly cheat widows out of their property and then pretend to be pious by making long prayers in public. Because of this, they will be severely punished."
Matthew Henry's Commentary on Luke 20:41-47
Commentary on Luke 20:39-47
(Read Luke 20:39-47)
The scribes commended the reply Christ made to the Sadducees about the resurrection, but they were silenced by a question concerning the Messiah. Christ, as God, was David's Lord; but Christ, as man, was David's son. The scribes would receive the severest judgement for defrauding the poor widows, and for their abuse of religion, particularly of prayer, which they used as a pretence for carrying on worldly and wicked plans. Dissembled piety is double sin. Then let us beg of God to keep us from pride, ambition, covetousness, and every evil thing; and to teach us to seek that honour which comes from him alone.
