2 Samuel 11:1-6, 12-15

And it came to pass, after the year was expired, at the time when kings go forth to battle, that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David tarried still at Jerusalem. 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 enquired after the woman. And one said, Is not this Bath-sheba, 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. And David sent to Joab, saying, Send me Uriah the Hittite. And Joab sent Uriah to David.

And David said to Uriah, Tarry here to day also, and to morrow I will let thee depart. So Uriah abode in Jerusalem that day, and the morrow. And when David had called him, he did eat and drink before him; and he made him drunk: and at even he went out to lie on his bed with the servants of his lord, but went not down to his house. And it came to pass in the morning, that David wrote a letter to Joab, and sent it by the hand of Uriah. And he wrote in the letter, saying, Set ye Uriah in the forefront of the hottest battle, and retire ye from him, that he may be smitten, and die.
