2 Samuel 11:13 (KJV)

And Uriah said unto David, The ark, and Israel, and Judah, abide in tents; and my lord Joab, and the servants of my lord, are encamped in the open fields; shall I then go into mine house, to eat and to drink, and to lie with my wife? as thou livest, and as thy soul liveth, I will not do this thing.

And David said to Uriah, Tarry here to day also, and to morrow I will let thee depart. So Uriah abode in Jerusalem that day, and the morrow.

And when David had called him, he did eat and drink before him; and he made him drunk: and at even he went out to lie on his bed with the servants of his lord, but went not down to his house.

And it came to pass in the morning, that David wrote a letter to Joab, and sent it by the hand of Uriah.

And he wrote in the letter, saying, Set ye Uriah in the forefront of the hottest battle, and retire ye from him, that he may be smitten, and die.
