“If David then call him Lord, how is he his son?”
King James Version (KJV)
22:43 How doth David then by the Spirit - By inspiration, call him Lord? If he be merely the son (or descendant) of David? If he be, as you suppose, a mere man, the son of a man?
22:44 The Lord said to my Lord - This his dominion, to which David himself was subject, shows both the heavenly majesty of the king, and the nature of his kingdom. Sit thou on my right hand - That is, remain in the highest authority and power. #Psalm 110:1|.
22:46 Neither durst any question him any more - Not by way of ensnaring or tempting him.
Mt 22:45 How is he his son? The answer is not given here, but plain. Christ, the Son of David, according to earthly descent, is the Son of God, God manifest in the flesh.
