Mark 12:35-37 New English Translation (NET Bible)
The Messiah: David’s Son and Lord
35 While Jesus was teaching in the temple courts, he said, “How is it that the experts in the law say that the Christ is David’s son? 36 David himself, by the Holy Spirit, said,
‘The Lord said to my lord,
37 If David himself calls him ‘Lord,’ how can he be his son?” And the large crowd was listening to him with delight.
