2 Samuel 11:18-21

18Then Joab sent and told David all the news about the fighting. 19And he instructed the messenger, “When you have finished telling all the news about the fighting to the king, 20then, if the king’s anger rises, and if he says to you, ‘Why did you go so near the city to fight? Did you not know that they would shoot from the wall? 21Who killed Abimelech the son of Jerubbesheth? Did not a woman cast an upper millstone on him from the wall, so that he died at Thebez? Why did you go so near the wall?’ then you shall say, ‘Your servant Uriah the Hittite is dead also.’”
