Babylon is suddenly fallen... — The form of announcement seems taken in part from Isaiah 21:9.
Take balm for her pain... — The words are significant. The captive people are not invited simply to raise a shout of triumph at the fall of their oppressor: they are to “take balm” (comp. the use of the same image in Jeremiah 8:22; Jeremiah 46:11), and try to heal her. They are still to “seek the peace of the city” (Jeremiah 29:7), to render kindly service, to pour balm into the bleeding wounds.
