Matthew 22:34-46 (NRSV)
The Greatest Commandment
34 When the Pharisees heard that he had silenced the Sadducees, they gathered together, 35 and one of them, a lawyer, asked him a question to test him. 36 “Teacher, which commandment in the law is the greatest?” 37 He said to him, “‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ 38 This is the greatest and first commandment. 39 And a second is like it: ‘You shall love your neighbor as yourself.’ 40 On these two commandments hang all the law and the prophets.”
The Question about David’s Son
41 Now while the Pharisees were gathered together, Jesus asked them this question: 42 “What do you think of the Messiah?[a] Whose son is he?” They said to him, “The son of David.” 43 He said to them, “How is it then that David by the Spirit[b] calls him Lord, saying,
44 ‘The Lord said to my Lord,
“Sit at my right hand,
until I put your enemies under your feet”’?
45 If David thus calls him Lord, how can he be his son?” 46 No one was able to give him an answer, nor from that day did anyone dare to ask him any more questions.
