ציטירנדיקער פּירוש אויף ירמיהו 49:21

נסו לקולם, “they fled when hearing their sounds”. This is a reference to the outcries of the people being swallowed by the earth. We know of a parallel in Jeremiah 49,21: מקול נפלם רעשה כל הארץ, “at the sound of their downfall the whole earth will shake.”

נסו לקולם, when they cried out at the time when they fell into the bowels of the earth. Compare Jeremiah 49,21 לקול נפלם רעשה ארץ, “the earth itself shook when it heard the sound of their downfall.”
