Charles Ellicott Commentary Jeremiah 37:1

"And Zedekiah the son of Josiah reigned as king, instead of Coniah the son of Jehoiakim, whom Nebuchadrezzar king of Babylon made king in the land of Judah." — Jeremiah 37:1 (ASV)

And king Zedekiah the son of Josiah ... —The eight chapters that follow form a continuous narrative of the later work and fortunes of the prophet. They open with recording the accession of Zedekiah, following on the deposition of Coniah or Jeconiah. Here, as in Jeremiah 22:24, we have the shortened form of the name of the latter. The relative pronoun whom Nebuchadrezzar ... made king refers to Zedekiah.
