The prophet, having detailed God’s past mercies to David, now passes on to direct prophecy, and that one of the most important in the O d Testament.
I will set up the seed - In one sense this mannifestly refers to Solomon, David’s successor and the builder of the temple. But we have the direct authority of Peter Acts 2:30 for applying it to Christ the seed of David, and His eternal kingdom; and the title the Son of David given to the Messiah in the rabbinical writings, as well as its special application to Jesus in the New Testament, springs mainly from the acknowledged Messianic significance of this prophecy. (See also Isaiah 55:3; Acts 13:34.)
