Matthew 22:42-45 NIV

[42] “What do you think about the Messiah? Whose son is he?” “The son of David,” they replied. [43] He said to them, “How is it then that David, speaking by the Spirit, calls him ‘Lord’? For he says, [44] “ ‘The Lord said to my Lord: “Sit at my right hand until I put your enemies under your feet.” ’ [45] If then David calls him ‘Lord,’ how can he be his son?”
