Job 7:3 - Joseph Benson’s Commentary on the Old and New Testaments

So am I made to possess, &c. This word, so, respects not so much the desire of a hired servant, as the cause of it, his hard toil and service. He means, God hath allotted me these painful sufferings, as he hath allotted to a hired servant hard labour. Months of vanity Months empty and unsatisfying, or false and deceitful, not affording me the ease and rest which they promised me, and I expected. He terms them months, rather than days, to signify the tediousness of his affliction. And wearisome nights He mentions nights, because that is the saddest time for sick and miserable persons; the darkness and solitude of the night being of themselves uncomfortable, and giving them more opportunity for solemn and sorrowful reflections.
