Job 7:8

Is there not an appointed time to man upon earth? are not his days also like the days of an hireling?

As a servant earnestly desireth the shadow, and as an hireling looketh for the reward of his work:

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

When I lie down, I say, When shall I arise, and the night be gone? and I am full of tossings to and fro unto the dawning of the day.
