Quote - Daniel viewed the 70 years as being "the desolation of Jerusalem." It wasn't servitude alone. – end quote
This prophecy did not apply to Jerusalem alone and the 70 years are in fact in regards to the time period that the nations would have to serve Babylon.
[Jeremiah 25:8…and I will bring them against this land and against its inhabitants and against all these nations round about; and I will devote them to destruction and make them an object of astonishment and something to whistle]
[Jeremiah 25:17 And I proceeded to take the cup out of the hand of Jehovah and to make all the nations drink to whom Jehovah had sent me: 18 namely, Jerusalem and the cities of Judah and her kings, her princes, to make them a devastated place, an object of astonishment, something to whistle at and a malediction, just as at this day; 19 Phar´aoh the king of Egypt and his servants and his princes and all his people; 20 and all the mixed company, and all the kings of the land of Uz, and all the kings of the land of the Phi·lis´tines and Ash´ke·lon and Ga´za and Ek´ron and the remnant of Ash´dod; 21 E´dom and Mo´ab and the sons of Am´mon; 22 and all the kings of Tyre and all the kings of Si´don and the kings of the island that is in the region of the sea; 23 and De´dan and Te´ma and Buz and all those with hair clipped at the temples; 24 and all the kings of the Arabs and all the kings of the mixed company who are residing in the wilderness; 25 and all the kings of Zim´ri and all the kings of E´lam and all the kings of the Medes; 26 and all the kings of the north who are near and far away, one after the other, and all the [other] kingdoms of the earth that are on the surface of the ground; and the king of She´shach himself will drink after them]
[Jeremiah 25:11 And all this land must become a devastated place, an object of astonishment, and these nations will have to serve the king of Babylon seventy years.”’ 12 “‘And it must occur that when seventy years have been fulfilled I shall call to account against the king of Babylon and against that nation,’ is the utterance of Jehovah,]
[Daniel 9:2 in the first year of his reign I, Daniel, discerned by the books the number of years mentioned in the word of Jehovah to Jeremiah the prophet to fulfill the desolation of Jerusalem, namely, 70 years.]
What is in yellow is the word of Jehovah to Jeremiah.
