David Commits Adultery with Bathsheba

11 In the spring of the year, the time when kings go out to battle, David sent Joab with his officers and all Israel with him; they ravaged the Ammonites, and besieged Rabbah. But David remained at Jerusalem.

² It happened, late one afternoon, when David rose from his couch and was walking about on the roof of the king’s house, that he saw from the roof a woman bathing; the woman was very beautiful.
