David called Jesus his Lord in the Book of Psalms and mentioned by Jesus in Luke 20:41-44.
Psalms 110:1-2
[1]The Lord said to my lord, “Sit here at my right until I put your enemies under your feet.”
[2]From Zion the Lord will extend your royal power. “Rule over your enemies,” he says.
Luke 20:41-44
[41]Jesus asked them, “How can it be said that the Messiah will be the descendant of David?
[42]For David himself says in the book of Psalms, ‘The Lord said to my Lord: Sit here on my right
[43]until I put your enemies as a footstool under your feet.’
[44]David called him ‘Lord’; how, then, can the Messiah be David’s descendant?”
