Is there not an appointed time to man upon earth? - Margin, or, warfare. The word used here צבא tsâbâ' means properly a host, an army, see the notes, Isaiah 1:9; then it means warfare, or the hard service of a soldier; notes, Isaiah 40:2. Here it means that man on the earth was enlisted, so to speak, for a certain time. He had a certain and definite hard service to perform, and which he must continue to discharge until he was relieved by death. It was a service of hazard, like the life of a soldier, or of toil, like that of one who had been hired for a certain time, and who anxiously looked for the period of his release. The object of Job in introducing this remark evidently is, to vindicate himself for the wish to die which he had expressed. He maintains that it is as natural and proper for man in his circumstances to wish to be released by death, as for a soldier to desire that his term of service might be accomplished, or a weary servant to long for the shades of the evening. The Septuagint renders it, “Is not the life of man upon the earth peirateerion “ - explained by Schleusner and rendered by Good, as meaning a band of pirates. The Vulgate renders it, militia - miltary service. The sense is, that the life of man was like the hard service of a soldier; and this is one of the points of justification to which Job referred in Job 6:29-30. He maintains that it is not improper to desire that such a service should close.
The days of an hireling - A man who has been hired to perform some service with a promise of a reward, and who is not unnaturally impatient to receive it. Job maintained that such was the life of man. He was looking forward to a reward, and it was not unnatural or improper to desire that that reward should be given to him.
