Job 15:21 New English Translation

²¹Terrifying sounds fill^[a] his ears;
in a time of peace marauders^[b] attack him.

Job 15:21 tn The word “fill” is not in the Hebrew text, but has been supplied in the translation.
Job 15:21 tn The word שׁוֹדֵד (shoded) means “a robber; a plunderer” (see Job 12:6). With the verb בּוֹא (boʾ ) the sentence means that the robber pounces on or comes against him (see GKC 373 §118.f). H. H. Rowley observes that the text does not say that he is under attack, but that the sound of fears is in his ears, i.e., that he is terrified by thoughts of this.
