Tafsiran Yeremia 37:1: Rashi & Abarbanel

reigned as king Since from now on, i.e., from this point, he comes to tell and to say that the retributions that he prophesied until now were fulfilled, he started to tell in this manner, that when the time of the visitation, when the days drew near that the words should be fulfilled, another king reigned over Judah instead of Coniah the son of Jehoiakim, etc.

Zedekiah, son of Josiah, became king in place of Jehoiachin, son of Jehoiakim, and the account continues until “the king Zedekiah sent.” Because the prophet had predicted that due to Jehoiakim's burning of the scroll, he would not have a son to sit on David's throne, the narrative immediately follows with the account of Zedekiah’s ascension to the throne, indicating that Zedekiah ruled in place of Jehoiakim, after Jehoiachin, his son. This means that although Jehoiachin briefly ruled Judah under the power of the king of Egypt, fulfilling God’s curse on Jehoiakim, his reign only lasted three months. Nebuchadnezzar then came, exiled him, and placed Zedekiah on the throne, thereby fulfilling Jeremiah's prophecy.
