I had kept to my custom of spending an occasional night on my rooftop muffled in my cloak. We who are old do not need so much sleep, and I could think and write in my head the pages I would write the next day.

“Lord, what shall I do there? I am not needed and King Saul has not called me,” I murmured.
The Voice said, “Go to Gibeah.” And that was all.
