Judges 9:48-49
48 he and all his men went up Mount Zalmon. He took an ax and cut off some branches, which he lifted to his shoulders. He ordered the men with him, “Quick! Do what you have seen me do!”
49 So all the men cut branches and followed Abimelech. They piled them against the stronghold and set it on fire over the people inside. So all the people in the tower of Shechem, about a thousand men and women, also died.
