1 Chronicles 3:15

The firstborn Johanan This Johanan is thought by many to be the same with Jehoahaz, who succeeded Josiah in the throne. But it seems more probable, as he is not mentioned in the book of Kings nor elsewhere in the Scriptures, that he died before his father. The fourth Shallum Of whom, at least under that name, there is no mention in the history of the reign of Josiah's sons in 2 Kings: but in Jer 22:11 there is mention of Shallum the son of Josiah, king of Judah, who reigned instead of Josiah his father; whom most conceive to be the same, who is otherwise called Jehoahaz, 2 Kings 23. And this seems most probable, 1st, From that phrase, He reigned instead of Josiah, which implies that he immediately succeeded his father, otherwise he would have been said to have reigned instead of his brother, as Zedekiah is said to have reigned instead of Jehoiachin, 2 Kings 24:17. 2d, From the order of that discourse of Jeremiah, which was directed to Zedekiah, and his servants, and people, and whom he admonisheth by the examples of the kings his predecessors, and of the sentence of God concerning each of them, and that in the order in which they reigned; of Shallum, 2 Kings 24:11, &c.; of Jehoiakim, 2 Kings 24:18, &c.; of Jechoniah or Coniah, Jeremiah 22:28. 3d, From the nature of that prophecy, Jeremiah 22:11, delivered concerning Shallum, which perfectly agrees to Jehoahaz, who was carried captive, not so far as Babylon, but only to Egypt, a very near country; whence the people hoped that he would speedily and easily return, or be re-established in his throne by the king of Egypt, in opposition to the king of Babylon. 4th, Because Jehoahaz was one of Josiah's younger sons, (2 Kings 23:31; 2 Kings 23:36,) and this Shallum is here called his fourth son.
