Judges 9:50-53

50Abimelech moved on to Thebez; he besieged and captured it.

51There was a fortified tower in the center of the city, so all the men and women, as well as the city’s leaders, ran into it and locked the entrance. Then they went up to the roof of the tower.

52Abimelech came and attacked the tower. When he approached the entrance of the tower to set it on fire,

53a woman threw an upper millstone down on his head and shattered his skull.
