Matthew 22:41-46 NIV
While the Pharisees were gathered together, Jesus asked them, “What do you think about the Messiah? Whose son is he?”
“The son of David,” they replied.
He said to them, “How is it then that David, speaking by the Spirit, calls him ‘Lord’? For he says,
“ ‘The Lord said to my Lord:
“Sit at my right hand
until I put your enemies
under your feet.” ’
If then David calls him ‘Lord,’ how can he be his son?” No one could say a word in reply, and from that day on no one dared to ask him any more questions.
