2 Samuel 11:2-5

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. David sent someone to inquire about the woman. It was reported, “This is Bathsheba daughter of Eliam, the wife of Uriah the Hittite.” So David sent messengers to get her, and she came to him, and he lay with her. (Now she was purifying herself after her period.) Then she returned to her house. The woman conceived; and she sent and told David, “I am pregnant.”
