"“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.” GC 326.1"
"Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy."
The EGW passage directly quotes Daniel 9:24. This is a clear and undeniable explicit allusion.
"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."
The EGW passage directly quotes Daniel 9:25. This is a clear and undeniable explicit allusion.
"And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined."
The EGW passage directly quotes Daniel 9:26. This is a clear and undeniable explicit allusion.
"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, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate."
EGW directly quotes Daniel 9:27.
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 8, 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 commandmen…
"Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy."
EGW directly quotes and interprets Daniel 9:24 in the context of the 70 weeks prophecy.
"And he said unto me, Unto two thousand and three hundred days; then shall the sanctuary be cleansed."
EGW directly quotes and interprets Daniel 8:14 in the context of the 2300 days prophecy.
"And he informed me, and talked with me, and said, O Daniel, I am now come forth to give thee skill and understanding."
EGW refers to the angel being sent to give Daniel understanding, which is mentioned in Daniel 9:22. While not a direct quote, it's a clear reference to the same event.
"In the seventh chapter of Ezra the decree is found. Verses 12-26 . In its completest form it was issued by Artaxerxes, king of Persia, 457 B.C. But in Ezra 6:14 the house of the Lord at Jerusalem is said to have been built “according to the commandment [“decree,” margin] of Cyrus, and Darius, and Artaxerxes king of Persia.” These three kings, in originating, reaffirming, and completing the decree, brought it to the perfection required by the prophecy to mark the beginning of the 2300 years. Taking 457 B.C., 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. GC 326.3"
"And the elders of the Jews builded, and they prospered through the prophesying of Haggai the prophet and Zechariah the son of Iddo. And they builded, and finished it, according to the commandment of the God of Israel, and according to the commandment of Cyrus, and Darius, and Artaxerxes king of Persia."
