2 Samuel 11:18-21

18Then Joab sent and told David all the things concerning the war,

19and charged the messenger, saying, “When you have finished telling the matters of the war to the king,

20if it happens that the king’s wrath rises, and he says to you: ‘Why did you approach so near to the city when you fought? Did you not know that they would shoot from the wall?

21Who struck Abimelech the son of Jerubbesheth? Was it not a woman who cast a piece of a millstone on him from the wall, so that he died in Thebez? Why did you go near the wall?’—then you shall say, ‘Your servant Uriah the Hittite is dead also.’ ”
