From off his bed; where he had lain and slept for some time; being possibly disposed to sleep after dinner, by reason of some excess committed in eating or drinking; and indulging himself in his lazy humour, which may seem very improper for so great a prince and captain, who had so many and great burdens upon his shoulders, especially in a time of war; and therefore such practices have been condemned by heathens; and Homer will not allow a general and great counsellor to sleep all the night, much less to take any part of the day for it. And therefore this is thought to be David's first error, and the occasion of his following fall. Walked upon the roof; which was plain, after the manner, Deuteronomy 22:8. Washing herself, to wit, in a bath, which possibly was in her garden, or in some room near to the king's palace, where she might wash herself divers ways, and for different ends; either for health, or coolness, or to cleanse herself from some kind of legal impurity; where also, the windows being open, and she careless, David might espy her.
