2 Samuel 11:13-17
English Standard Version
14In the morning David wrote a letter to Joab and sent it by the hand of Uriah.
15In the letter he wrote, "Set Uriah in the forefront of the hardest fighting, and then draw back from him, that he may be struck down, and die."
16And as Joab was besieging the city, he assigned Uriah to the place where he knew there were valiant men.
17And the men of the city came out and fought with Joab, and some of the servants of David among the people fell. Uriah the Hittite also died.
