2 Samuel 11:1-2

In the spring, when the kings normally went out to war, David sent out Joab, his servants, and all the Israelites. They destroyed the Ammonites and attacked the city of Rabbah. But David stayed in Jerusalem. One evening David got up from his bed and walked around on the roof of his palace. While he was on the roof, he saw a woman bathing. She was very beautiful.
