For now should I have lain down and been quiet; I should have slept; then had I been at rest,
For now should I have lain still and been quiet, I should have slept: then had I been at rest,
For then would I have lain down and been quiet; I would have slept; then would I have been at rest [in death]
For now I would be lying down quietly; I’d sleep; rest would be mine
For by now, I should have been sleeping silently, and taking rest in my sleep
