2 Samuel 11:13-15
11:13 Then David summoned him. He ate and drank with him, and got him drunk. But in the evening he went out to sleep on his bed with the servants of his lord; he did not go down to his own house.
11:14 In the morning David wrote a letter to Joab and sent it with Uriah.
11:15 In the letter he wrote: “Station Uriah in the thick of the battle and then withdraw from him so he will be cut down and killed.”
