All the women that are left; i.e. probably the wives of Zedekiah's royal predecessors, who had passed into his own harem as concubines. Even Hezekiah, as Payne Smith well points out, had a numerous harem ('Records of the Past,' 1:39, where "daughters" is equivalent to "girls").
Zedekiah's own wives are spoken of in the next verse. Thy friends have set thee on, etc. The first half of this taunting song (mashal) reminds of Obadiah 1:7 (for other points of contact with Obadiah, see on Jeremiah 49:7-22).
The meaning is that, after urging the weak-minded Zedekiah on to a conflict with the Chaldeans, they have left him involved in hopeless difficulties.
