Yet God had bidden His messenger, “Make this man to understand the vision.” That commission must be fulfilled. In obedience to it, the angel, some time afterward, returned to Daniel, saying, “I am now come forth to give thee skill and understanding;” “therefore understand the matter, and consider the vision.”(539) There was one important point in the vision of chapter eight which had been left unexplained, namely, that relating to time,—the period of the 2300 days; therefore the angel, in resuming his explanation, dwells chiefly upon the subject of time: “Seventy weeks are determined upon thy people and upon thy holy city.... Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times. And after threescore and two weeks shall Messiah be cut off, but not for Himself.... And He shall confirm the covenant with many for one week: and in the midst of the week He shall cause the sacrifice and the oblation to cease.” The angel had been sent to Daniel for the express purpose of explaining to him the point which he had failed to understand in the vision of the eighth chapter, the statement relative to time,—“Unto two thousand and three hundred days; then shall the sanctuary be cleansed.” After bidding Daniel “understand the matter, and consider the vision,” the very first words of the angel are, “Seventy weeks are determined upon thy people and upon thy holy city.” The word here translated “determined,” literally signifies “cut off.” Seventy weeks, representing 490 years, are declared by the angel to be cut off, as specially pertaining to the Jews. But from what were they cut off? As the 2300 days was the only period of time mentioned in chapter eight, it must be the period from which the seventy weeks were cut off; the seventy weeks must therefore be a part of the 2300 days, and the two periods must begin together. The seventy weeks were declared by the angel to date from the going forth of the commandment to restore and build Jerusalem. If the date of this commandment could be found, then the starting-point for the great period of the 2300 days would be ascertained. In the seventh chapter of Ezra the decree is found.(540) In its completest form it was issued by Artaxerxes, king of Persia, B.C. 457. But in Ezra 6:14 the house of the Lord at Jerusalem is said to have been built “according to the commandment [margin, decree] of Cyrus, and Darius, and Artaxerxes king of Persia.” These three kings, in originating, re-affirming, and completing the decree, brought it to the perfection required by the prophecy to mark the beginning of the 2300 years. Taking B.C. 457, the time when the decree was completed, as the date of the commandment, every specification of the prophecy concerning the seventy weeks was seen to have been fulfilled.
