Adam Clarke on Job 7:4

When I lie down - I have so little rest, that when I do lie down I long for the return of the light, that I may rise. Nothing can better depict the state of a man under continual afflictions, which afford him no respite, his days and his nights being spent in constant anguish, utterly unable to be in any one posture, so that he is continually changing his position in his bed, finding ease nowhere: thus, as himself expresses it, he is full of tossings.
