2 Samuel 11:20-21

20the king may become angry. He might ask you, ‘Why did you go so close to the city to fight? Didn’t you know they would shoot from the wall?

21Who killed Jerubbesheth’s  son Abimelech? Didn’t a woman on the wall of Thebez throw a small millstone at him and kill him? Why did you go so close to the wall?’ If the king asks this, then say, ‘Your man Uriah the Hittite is also dead.’ ”
