Judges 9:49-53

So all the people also cut down, each one, his branch and followed Abimelech, and put them on top of the inner chamber and set the inner chamber on fire over those inside, so that all the people of the tower of Shechem also died, about a thousand men and women.

Then Abimelech went to Thebez, and he camped against Thebez and captured it.

But there was a strong tower in the center of the city, and all the men and women with all the leaders of the city fled there and shut themselves in; and they went up on the roof of the tower.

So Abimelech came to the tower and fought against it, and approached the entrance of the tower to burn it down with fire.

But a woman threw an upper millstone on Abimelech’s head, crushing his skull.
