Chronology

The entire period from king Josiah to the destruction of Jerusalem is a little over 50 years. Five kings reigned during this period. Josiah was slain by Pharaoh-nechoh and the people made his son king, Jehoahaz (also known as Shallum) (2 Kings 23:29-30). Jehoahaz was taken captive by Pharaoh-nechoh who made Jehoiakim (Eliakim), another son of Josiah, king in his stead (2 Kings 23:33, 34). Jehoiakim ended his reign as a vassal of the king of Babylon (2 Kings 24:1). Daniel was a captive during this time (Dan. 1:1).
Jehoiachin (Jechoniah, Coniah), a grandson of Josiah and the son of Jehoiakim, became the fourth king. Jehoiachin was taken captive by Nebuchadnezzar king of Babylon along with the able-bodied men of the land (2 Kings 24:15, 16). Ezekiel was included amongst their number (Ezek. 1:2). Zedekiah (Mattaniah), a third son of Josiah, and the last king of Judah, was made king by Nebuchadnezzar and taken captive by him (2 Kings 24:17, 25:7).
Zedekiah’s reign was replaced with the governorship of Gedaliah, whom Ishmael (of royal descent) murdered (2 Kings 25:25). Only Josiah and Jechoniah are mentioned in the genealogy of Matthew.
It was a time of profound change during which God was setting aside Israel and placing His government in the hands of a Gentile nation. Recognizing this is key to understanding these books.
