Mark 12:36
David himself, speaking by the Holy Spirit, declared: the Lord said to my Lord, sit at my right hand until I put your enemies under your feet — Psalm 110:1 is quoted: David himself, speaking by the Holy Spirit, calls the Messiah my Lord. If the Messiah is merely David's descendant, David would not call him Lord — a son is not his father's lord. The Psalm's testimony that David called the Messiah Lord implies that the Messiah's identity transcends the son-of-David category.
