1 Chronicles 3:16

Of the above four brothers, sons of Josiah, the second, Jehoiakim, or Eliakim, had a son called Jeconiah , or Jehoiachin—essentially the same word. He was eighteen years of age when he succeeded his father ( 2 Kings 24:8 ). A touching glimpse is given of him in Jeremiah 52:31 . His name is shortened to Coniah in Jeremiah 22:24 and Jeremiah 37:1 , though elsewhere in the same prophet, Jeconiah, and in one place ( Jeremiah 52:31 ), Jehoiachin. The name of Zedekiah occasions difficulty in this verse. In the first instance, following the examples of Jeremiah 37:10-14 , we should presume that this Zedekiah is set forth as a son of Jeconiah, and as it is not said that he reigned after Jeconiah (for it was undoubtedly Jeconiah's uncle Zedekiah who reigned after him), we need only have read it as a statement of one of his sons. Against this, however, there are two tolerably decisive considerations; for, first , the verse opens confessedly by offering us sons of Jehoiakim , and these two, Jeconiah and Zedekiah, will fulfil the promise of that plural; and again, the seventeenth verse enters upon the formal enumeration of sons to Jeconiah. The question, therefore, returns—Who was this Zedekiah, son of Jehoiakim? Some consider him identical with the Zedekiah of the previous verse, and that "his son" means here "his successor." This undoes fewer difficulties than it makes. If the text be not corrupt, the likeliest solution is to suppose that this Zedekiah of Jeremiah 37:16 is an otherwise unknown brother of Jeconiah, and son of Jehoiakim.
