Judges 9:46-49

46When all the leaders of the Tower of Shechem heard of it, they entered the stronghold of the house of El-berith.

47Abimelech was told that all the leaders of the Tower of Shechem were gathered together.

48And Abimelech went up to Mount Zalmon, he and all the people who were with him. And Abimelech took an axe in his hand and cut down a bundle of brushwood and took it up and laid it on his shoulder. And he said to the men who were with him, "What you have seen me do, hurry and do as I have done."

49So every one of the people cut down his bundle and following Abimelech put it against the stronghold, and they set the stronghold on fire over them, so that all the people of the Tower of Shechem also died, about 1,000 men and women.
