2 Samuel 11:2-4

One evening David got up from his couch and was walking on the [flat] roof of the king’s palace, and from there he saw a woman bathing; and she was very beautiful in appearance. David sent word and inquired about the woman. Someone said, “Is this not Bathsheba, the daughter of Eliam, the wife of Uriah the Hittite?” David sent messengers and took her. When she came to him, he lay with her. And when she was purified from her uncleanness, she returned to her house.
