Scholar, Pharoah Necho’s campaign in northern Syria coincides with the brief reign of Jehoahaz, who was deposed on Necho’s return shortly after 1 Tishri (late Sept) 609, at which time Jehoiakim’s accession begins. First year of Jehoiakim, Tishri 608 (Sept–Oct) to Elul 607 (Aug–Sept). Third year of Jehoiakim, Tishri 606 (Sept–Oct) to last of Elul, 605 (Oct 6). This is the twenty-first year of Nabopolasar and the accession year of Nebuchadrezzar. The latter agrees with Ptolemy’s Canon, Nabonidus Harran Stele (NABON H 1, B), VAT 4956 and many Business tablets. As you will notice, the destruction of Jerusalem is still a long way off, so 607 is not on the menu.
Battle of Carchemish, late May to early June 605; Nabopolasar’s death Aug 15/16, 605. Nebuchadrezzar’s coronation Sept 7, 605. The accession year of Nebuchadrezzar = the third year of Jehoiakim. First (regnal) year of Nebuchadrezzar = the fourth year of Jehoiakim. See A. R. Green (1982). “The Chronology of the Last Days of Judah: Two Apparent Discrepancies.” Journal of Biblical Literature, 101, pp. 57–73.
Jehoiakim reigned 11 years in Jerusalem (2 Kings 23:36). Dan. 1:1, 2 encompasses a period of 8 years. At the beginning of the eight years, in 605 BCE, Daniel and his companions would be deported (Dan. 1:1, 3). At the end of the eight years, in 597, Jehoiakim would be deposed, and some of the temple utensils taken (2 Chron. 36:5-7; Jer. 52:28; Dan. 1:2). Next followed Jehoiachin’s appointment, lasting only three months. Nebuchadrezzar, in his 8th year, would take 8000 into exile, including Jehoiachin. All remaining temple utensils would be taken (2 Kings 24:10-16; 2 Chron. 36:9, 10). This proves that the deportations do not have to be associated with the siege and capture of Jerusalem. Even after the fall of Jerusalem, during Nebuchadrezzar’s 18th year, the land was not left completely desolate. Jeremiah reports a final deportation in Nebuchadrezzar’s 23rd year.
Josephus would follow Daniel:
"Josephus elsewhere describes the destruction of Jerusalem by the Babylonians and then says that “all Judea and Jerusalem, and the temple, continued to be a desert for seventy years” (Josephus, Antiquities of the Jews X, ix, 7 [10.184]). He pointedly states that “our city was desolate during the interval of seventy years, until the days of Cyrus” (Josephus, Against Apion I, 19 [1.132]). Here he shares the misconception of a later editor and/or redactor of the book of Daniel, “fulfilling the devastations of Jerusalem, [namely,] seventy years” (cf. Dan. 9:2)."
Jerusalem was not left desolate for seventy years. Here's that scribal error I was referring to:
Devastations vs. reproach. In the OG we have ὀνειδισμός, meaning “reproach” (singular). See NETS. This is viewed as an error in transmission: Jer. 25:9 καὶ εἰς ὀνειδισμόν and (I turn them) into a disgrace ולחרפות is read for MT ולחרבת and (I will turn them) into desolations. However, as seen, Dan. 9:2 is not drawn from Jer. 29:10, but Jer. 25:9-12. Here it could mean “reproach, disgrace, insult” (cf. Jer. 18:16; 19:8; Ezek. 5:13, 14). Specifically Jer. 25:9 וְלִשְׁרֵקָ֔ה וּלְחָרְב֖וֹת עוֹלָֽם , “and something to whistle at and places devastated to time indefinite.” LXX καὶ εἰς ὀνειδισμόν, ולחֶרְפַּת. See BHS footnote. KBLex, in accordance with the textcritical note suggests an emendation to לְחֶרְפַּת (“as a disgrace”). See J. Lust, E. Eynikel & K. Hauspie (2003). A Greek-English Lexicon of the Septuagint: Revised Edition. Deutsche Bibelgesellschaft: Stuttgart. According to secular chronology, Jerusalem did not lie desolate for seventy years, but her reproach and humiliation could have started with Jehoiakim’s three year servitude, completing Jeremiah’s seventy year cycle (2 Kings 24:1, 2; cf. Is. 25:9, 11).
