Charles Ellicott Commentary Jeremiah 30:15

"Why criest thou for thy hurt? thy pain is incurable: for the greatness of thine iniquity, because thy sins were increased, I have done these things unto thee." — Jeremiah 30:15 (ASV)

Why criest thou ...? —The personification of the previous verse is continued. The prophet looks on Judah—as in Lamentations 1:1-2 —as on some forlorn and desperate castaway stricken with pestilence, crying in the agony of her hopelessness; and he reminds her that she is but bearing the righteous punishment of her iniquities.

In accepting the law of retribution, as seen in her own sufferings, she might find hope for the future. Her oppressors also would come under that law. The wheel would come full circle, and the devourers would be themselves devoured.
