2 Samuel 11:21

11:21 Who struck down Abimelech the son of Jerub-Besheth? Didn’t a woman throw an upper millstone ¹  down on him from the wall so that he died in Thebez? Why did you go so close to the wall?’ just say to him, ‘Your servant Uriah the Hittite is also dead.’”

[11:21]  ¹ sn The upper millstone (Heb “millstone of riding”) refers to the heavy circular stone that was commonly rolled over a circular base in order to crush and grind such things as olives.
