15. The firstborn Johanan. This son must not be confused with Jehoahaz, who succeeded his father Josiah to the throne and who was deposed and exiled to Egypt by Necho after a reign of only three months.
The second Jehoiakim. He was also known as Eliakim, and succeeded Jehoahaz at the age of 25, having been placed on the throne of Judah by Necho of Egypt (2 Kings 23:34, 36).
The third Zedekiah. His name was changed from Mattaniah to Zedekiah when Nebuchadnezzar made him king. He was only 21 at the end of Jehoiakim’s 11-year reign (2 Kings 24:17, 18).
The fourth Shallum. This was Jehoahaz (2 Kings 23:30; Jer. 22:11). Shallum was the first son of Josiah to reign after his father’s death. He was placed upon the throne by the people of Judah after the death of Josiah (2 Kings 23:30). Jehoahaz was not the first-born son of Josiah, but was 2 years younger than Jehoiakim (see on 2 Kings 23:30, 36). The order of the sons of Josiah was, according to succession to the throne, Jehoahaz, Jehoiakim, Zedekiah; but according to age, Jehoiakim, Jehoahaz, Zedekiah. Shallum, or Jehoahaz, may here be listed as fourth because he reigned only 3 months, whereas his 2 brothers each reigned 11 years.
