How say they that Christ is David's son, &c. For an elucidation of these verses, see on Matthew 22:41-46; Matthew 23:5-7; Matthew 23:14; and Mark 12:35-40. David therefore calleth him Lord: how is he then his son “This implies both the existence of David in a future state, and the authority of the Messiah over that invisible world into which that prince was removed by death. Else, how great a monarch soever the Messiah might have been, he could not have been properly called David's Lord; any more than Julius Cesar could have been called the lord of Romulus, because he reigned in Rome seven hundred years after his death, and vastly extended the bounds of that empire which Romulus founded. Munster's note on this text shows, in a very forcible manner, the wretched expedients of some modern Jews to evade the force of that interpretation of the one hundred and tenth Psalm, which refers it to the Messiah.” Doddridge.
