Pharaoh 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. 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.
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 (Jer. 52:27-30). See A. R. Green (1982). “The Chronology of the Last Days of Judah: Two Apparent Discrepancies.” Journal of Biblical Literature, 101, pp. 57–73.
Land was never desolate for seventy years. The slavery of the nations under the Babylonians would last seventy years (Jer. 25:11).
