Job 3:21 New English Translation

²¹to^[a] those who wait^[b] for death that^[c] does not come,
and search for it^[d]
more than for hidden treasures,

Job 3:21 tn The verse simply begins with the participle in apposition to the expressions in the previous verse describing those who are bitter. The preposition is added from the context.
Job 3:21 tn The verb is the Piel participle of חָכָה (khakhah, “to wait for” someone; Yahweh is the object in Isa 8:17; 64:3; Ps 33:20). Here death is the supreme hope of the miserable and the suffering.
Job 3:21 tn The verse simply has the form אֵין (ʾen, “there is not”) with a pronominal suffix and a conjunction—“and there is not it” or “and it is not.” The LXX and the Vulgate add a verb to explain this form: “and obtain it not.”
Job 3:21 tn The parallel verb is now a preterite with a vav (ו) consecutive; it therefore has the nuance of a characteristic perfect or gnomic perfect—the English present tense.sn The verb חָפַר (khafar) means “to dig; to excavate.” It may have the accusative of the thing that is being sought (Exod 7:24), but here it is followed by a comparative min (מִן). The verse therefore describes the sufferers who excavate or dig the ground to find death, more than others who seek for treasure.
