Judges 9:39-49

39 And Ga'al went out at the head of the men of Shechem, and fought with Abim'elech.
40 And Abim'elech chased him, and he fled before him; and many fell wounded, up to the entrance of the gate.
41 And Abim'elech dwelt at Aru'mah; and Zebul drove out Ga'al and his kinsmen, so that they could not live on at Shechem.
42 On the following day the men went out into the fields. And Abim'elech was told.
43 He took his men and divided them into three companies, and laid wait in the fields; and he looked and saw the men coming out of the city, and he rose against them and slew them.
44 Abim'elech and the company that was with him rushed forward and stood at the entrance of the gate of the city, while the two companies rushed upon all who were in the fields and slew them.
45 And Abim'elech fought against the city all that day; he took the city, and killed the people that were in it; and he razed the city and sowed it with salt.
46 When all the people of the Tower of Shechem heard of it, they entered the stronghold of the house of El-be'rith.
47 Abim'elech was told that all the people of the Tower of Shechem were gathered together.
48 And Abim'elech went up to Mount Zalmon, he and all the men that were with him; and Abim'elech 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 that were with him, "What you have seen me do, make haste to do, as I have done."
49 So every one of the people cut down his bundle and following Abim'elech 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 a thousand men and women.
