2 Samuel 11:14-17

Now in the morning David wrote a letter to Joab and sent it by the hand of Uriah. He had written in the letter, saying, “Place Uriah in the front line of the fiercest battle and withdraw from him, so that he may be struck down and die.” So it was as Joab kept watch on the city, that he put Uriah at the place where he knew there were valiant men. The men of the city went out and fought against Joab, and some of the people among David’s servants fell; and Uriah the Hittite also died.
