2 Samuel 11:14-17

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. And it came to pass, when Joab kept watch upon the city, that he assigned Uriah unto the place where he knew that valiant men were. And the men of the city went out, and fought with Joab: and there fell some of the people, even of the servants of David; and Uriah the Hittite died also.
