Matthew 22:41-45

Then, surrounded by the Pharisees, Jesus asked them a question: “What do you think about the Messiah? Whose son is he?” They replied, “He is the son of David.” Jesus responded, “Then why does David, speaking under the inspiration of the Spirit, call the Messiah ‘my Lord’? For David said, ‘The LORD said to my Lord, Sit in the place of honor at my right hand until I humble your enemies beneath your feet.’ Since David called the Messiah ‘my Lord,’ how can the Messiah be his son?”
