Jeremiah 39:11 - Ellicott's Commentary On The Whole Bible

Nebuchadrezzar king of Babylon.... — It is clear that Nebuchadrezzar had been well informed of the part which Jeremiah had taken from first to last in counselling submission. This he may have heard from the deserters named in Jeremiah 39:9, or even from the lips of Zedekiah. Possibly the journey to Euphrates, of which we read in Jeremiah 13:5, may, at even an earlier period, have brought the king and the prophet into contact. From the time of Nebuzar-adan’s arrival, the position of Jeremiah was obviously changed for the better, and he became an honoured and trusted counsellor. It appears from Jeremiah 40:1 that the prophet had at first been taken in chains to Ramah, with the other captives. Probably he had been sent back to Jerusalem when the others were carried off to Riblah, or Babylon (Jeremiah 39:6-9).
