For thus saith the Lord,.... Confirming the above promise concerning the Messiah; giving a reason why his coming may be expected; and why the salvation, justification, and final perseverance of his church and people, are certain things, and to be depended upon:David shall never want a man to sit upon the throne of the house of Israel; or, "there shall not be cut off unto David a man" ; and this is not to be understood of the temporal kingdom of David, which has been at an end long ago: Jeconiah, that was carried captive into Babylon, was written childless, and left no issue; and Zerubbabel, the only one of David's seed that made any figure after the captivity, was not a king; this is only true of the man Christ Jesus, of the seed of David, and is his son, to whom has been given the throne of his father David; and who reigns over the house of Jacob for ever; and of whose kingdom there is no end, Lu 1:32; and as long as he is King of saints, which will be for ever, David will not want a man to sit upon his throne.
David's earthly kingdom was but a typical and shadowy one; a type of Christ's spiritual kingdom, which has succeeded it, and in which Christ is David's son and successor, and whose kingdom is an everlasting kingdom.
