Judges 9:50-53

50Then Abimelech went to Thebez, and he encamped against Thebez and took it.

51But there was a strong tower in the city, and all the men and women—all the people of the city—fled there and shut themselves in; then they went up to the top of the tower.

52So Abimelech came as far as the tower and fought against it; and he drew near the door of the tower to burn it with fire.

53But a certain woman dropped an upper millstone on Abimelech’s head and crushed his skull.
