Job 7:1 New English Translation

7 “Does not humanity have hard service^[a] on earth?
Are not their days also like the days of a hired man?^[b]

Job 7:1 tn The word צָבָא (tsavaʾ) is actually “army”; it can be used for the hard service of military service as well as other toil. As a military term it would include the fixed period of duty (the time) and the hard work (toil). Job here is considering the lot of all humans, not just himself.
Job 7:1 tn The שָׂכִיר (sakhir) is a hired man, either a man who works for wages, or a mercenary soldier (Jer 46:21). The latter sense may be what is intended here in view of the parallelism, although the next verse seems much broader.
