Matthew 22:42-45
22:42 “What do you think about the Christ? Whose son is he?” They said, “The son of David.”
22:43 He said to them, “How then does David by the Spirit call him ‘Lord,’ saying,
22:44 ‘The Lord said to my lord,
“Sit at my right hand,
until I put your enemies under your feet”’?
22:45 If David then calls him ‘Lord,’ how can he be his son?”
