Then Thou spakest in vision to Thy holy one, to His saint and servant, namely, the prophet Nathan, who acted as God's representative in dealing with David, 2 Samuel 7, and saidst, I have laid help upon one that is mighty, upon a great champion; I have exalted one chosen out of the people, the immediate reference being to David, the son of Jesse, but the implied reference to David's Son and David's Lord, the Messiah. It is a distinguishing mark of prophecy often to identify events and persons near at hand with those at a far distance according to human understanding. We must always remember that with the Lord there are no reckonings of time, that all events, as far as He is concerned, happen in an everlasting now.
