Judges 9:49-51

Amplified Bible

⁴⁹ So everyone of the people also cut down his branch and followed Abimelech, and they put the branches on top of the inner chamber and set it on fire over those inside, so that all the people in the Tower of Shechem also died, about a thousand men and women.

⁵⁰ Then Abimelech went to Thebez, and camped against Thebez and took it. ⁵¹ But there was a strong (fortified) tower in the center of the city, and all the men and women with all the leaders of the city fled to it and shut themselves in; and they went up on the roof of the tower.
