Albert Barnes Commentary Jeremiah 37:14

"Then said Jeremiah, It is false; I am not falling away to the Chaldeans. But he hearkened not to him; so Irijah laid hold on Jeremiah, and brought him to the princes." — Jeremiah 37:14 (ASV)

The princes - Not the noblemen trained in the days of Josiah and Jeremiah’s friends (Jeremiah 26:16), but those described in (Jeremiah 24:8). They assumed that the accusation was true; they first scourged and then imprisoned Jeremiah.
