Judges 9:20, 49

But if not, may fire come out from Abimelech and devour the people of Shechem and Beth-millo; and may fire come out from the people of Shechem and Beth-millo, and devour Abimelech.”

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.
