As the time predicted by Daniel drew near, when “Messiah the Prince”—the anointed One—was to appear, the Jewish people could have reasoned, and undoubtedly did so, on this wise: The Messiah after the flesh is to be of the house and lineage of David, therefore his birth must be in that line; and according to the regulations of the Jewish law and customs, he must be anointed for public service at the age of thirty years; and if he is to appear as the anointed at that age, then his birth must be thirty years before the termination of the sixty-nine weeks of years, which are to extend to the coming of the Messiah.
