So am I made to possess months of vanity, and wearisome nights are appointed to me.

So I also have had empty months, and have numbered to myself wearisome nights.

So I have been caused to inherit months of vanity, And nights of misery they numbered to me.

So I have for my heritage months of pain to no purpose, and nights of weariness are given to me.

so also have I had empty months and have counted my burdensome nights.

So am I made to possess - Hebrew I am made to inherit. The meaning is, that such sad and melancholy seasons now were his only portion.
Months of vanity - That is, months which were destitute of comfort; in other words, months of affliction. How long his trials had continued before this, we have no means of ascertaining. There is no reason, however, to suppose that his bodily sufferings came upon him all at once, or that they had not continued for a considerable period. It is quite probable that his expressions of impatience were the result not only of the intensity, but the continuance of his sorrows.
And wearisome nights are appointed to me - Even his rest was disturbed. The time when care is usually forgotten and toil ceases, was to him a period of sleepless anxiety and distress - עמל ‛âmâl. The Septuagint renders it, nights of pangs (νύκτες ὀδυνῶν nuktes odunōn), expressing accurately the sense of the Hebrew. The Hebrew word עמל ‛âmâl is commonly applied to intense sorrow, to trouble and pain of the severest kind, such as the pains of parturition; see the notes at Isaiah 53:11.

So am I made to possess - But night is no relief to me, it is only a continuance of my anxiety and labor. I am like the hireling, I have my appointed labor for the day. I am like the soldier harassed by the enemy: I am obliged to be continually on the watch, always on the look out, with scarcely any rest.

So am I made to possess (b) months of vanity, and wearisome nights are appointed to me.
(b) My sorrow has continued from month to month, and I have looked for hope in vain.

So am I made to possess months of vanity,.... This is not a reddition or application of the above similes of the servant and hireling, Job 7:1; for that is to be understood, and to be supplied at the end of Job 7:2; that as those looked for the shadow and payment of hire, so Job looked for and earnestly desired death, or to be removed out of the world; besides, the things here instanced in do not answer; for Job, instead of having the refreshing shadow, had months of vanity, and instead of rest from his labours had nothing but wearisome nights, and continual tossings to and fro; whereas the sleep of a labouring man is sweet to him; and having laboured hard all day, the night is a time of rest to him; but so it was not with Job; wherefore this "so" refers to the common state and condition of mankind, in which Job was, with an addition of extraordinary afflictions upon him: the time of his afflictions, though but short, seemed long, and therefore is expressed by months; and some months might have passed from the time his calamities began to the present; since it must be some time before his friends heard of them, and more still before they could meet together and agree upon their coming, and were actually come to him; as also some time was spent in silence, and now in conversation with him; the Jews (p) make them to be twelve months: and these months were "months of vanity", or "empty" (q) ones; such as winter months, empty of all joy, and peace, and comfort; times in which he had no pleasure, no ease of body or of mind; destitute of the good things of life, and of the presence of God and communion with him; and full of trouble, sorrow, and distress: and these were "given him for an inheritance" (r); were his lot and portion, which he received as an inheritance from his parents, in consequence of original sin, the source of all the troubles and miseries of human life, in common with other men; and which were allotted him by his heavenly Father, according to his sovereign will and pleasure, as all the afflictions of the Lord's people are the inheritance bequeathed them by their Father, and the legacy of their Redeemer:
and wearisome nights are appointed to me; one after another, in succession; in which he could have no sleep nor rest, through pain of body and distress of mind; and so became the more weary, through long lying down and tossings to and fro, through groans and tears, and much watching; and these were prepared for him in the purposes of God, and appointed to him in his counsels and decrees; see Job 23:14; or they "prepared" or "appointed" (s); that is, "Elohim", the three Divine Persons.

Months of comfortless misfortune.
I am made to possess--literally, "to be heir to." Irony. "To be heir to," is usually a matter of joy; but here it is the entail of an involuntary and dismal inheritance.
Months--for days, to express its long duration.
Appointed--literally, "they have numbered to me"; marking well the unavoidable doom assigned to him.

So - This so respects not so much the desire of an hired servant, as the ground of it, his hard toil and service. Possess - God, hath given me this as my lot and inheritance. Months - So he calls them rather than days, to note the tediousness of his affliction. Vanity - Empty and unsatisfying. 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.
