2 Samuel 11:1-2 It happened in the spring of the year, at the time when kings go out to battle, that David sent Joab and his servants with him, and all Israel; and they destroyed the people of Ammon and besieged Rabbah. But David remained at Jerusalem.
2 Then it happened one evening that David arose from his bed and walked on the roof of the king's house. And from the roof he saw a woman bathing, and the woman was very beautiful to behold.
