2 Samuel 11:14-17

In the morning David wrote a letter to Joab and sent it with Uriah. He wrote in the letter, “Put Uriah in the front line of the heaviest fighting and leave him, so that he may be struck down and die.” So it happened that as Joab was besieging the city, he assigned Uriah to the place where he knew the [enemy’s] valiant men were positioned. And the men of the city came out and fought against Joab, and some of the people among the servants of David fell; Uriah the Hittite also died.
