2 Samuel 11:2-5
And it came to pass in an eveningtide, that David arose from off his bed, and walked upon the roof of the king's house: and from the roof he saw a woman washing herself; and the woman was very beautiful to look upon. And David sent and inquired after the woman. And one said, Is not this Bathsheba, the daughter of Eliam, the wife of Uriah the Hittite? And David sent messengers, and took her; and she came in unto him, and he lay with her; for she was purified from her uncleanness: and she returned unto her house. And the woman conceived, and sent and told David, and said, I am with child.
