queen - Nehushta, the queen mother, daughter of Elnathan (2Ki 24:8, 2Ki 24:15). (Elnathan, her father, is perhaps the same as the one mentioned in Jer 26:22). She reigned jointly with her son.
princes - All the men of authority were taken away lest they should organize a rebellion. Jeremiah wrote his letter while the calamity was still recent, to console the captives under it.
