2 Samuel 11:13-15

13Then David invited Uriah to eat and drink with him, and David got him drunk. He went out in the evening to lie down on his cot with his master’s servants, but he did not go home.

14The next morning David wrote a letter to Joab and sent it with Uriah.

15In the letter he wrote: Put Uriah at the front of the fiercest fighting, then withdraw from him so that he is struck down and dies.
