Judges 9:50

And all the people likewise cut down every man his bough, and followed Abimelech, and put them to the hold, and set the hold on fire upon them; so that all the men of the tower of Shechem died also, about a thousand men and women.

But there was a strong tower within the city, and thither fled all the men and women, and all they of the city, and shut it to them, and gat them up to the top of the tower.
