Albert Barnes Commentary Nahum 2:10

"She is empty, and void, and waste; and the heart melteth, and the knees smite together, and anguish is in all loins, and the faces of them all are waxed pale." — Nahum 2:10 (ASV)

She is empty and void and waste — The completeness of her judgment is declared first under that solemn number, three, and the three words in Hebrew are nearly the same, with the same meaning, only each word fuller than the former, as picturing a growing desolation; and then under four heads (seven in total), also picturing a growing fear.

First, the heart, the seat of courage, resolve, and high purpose, melteth; then the knees smite together, and they tremble and shake throughout their frame; then, much pain is in all loins, literally, “strong pains as of a woman in labor,” which writhes and doubles the whole body, makes it completely powerless and unable to stand upright, and will bow the very loins, the seat of strength (Proverbs 31:17); and, lastly, the faces of them all gather blackness (see the note at Joel 2:6), the result of extreme pain and the sign of approaching death.
