If I wait, the grave is mine house; rather, surely I look for the grave (Sheol) as my house; i.e. I expect no return of prosperity, no renewal of life in a sumptuous mansion, no recovery of the state and dignity from which I have fallen—I look only for Sheol as my future abode and resting-place -there, in Sheol, I have made my bed in the darkness; i.
e. I regard myself as already there, lying on my narrow bed in the darkness, at rest after my afflictions.
