Judges 9:42-45

42The next day the people of Shechem went out into the fields, and this was reported to Abimelech. 43So he took his men, divided them into three companies, and lay in wait in the fields. When he saw the people coming out of the city, he rose up against them and attacked them.

44Then Abimelech and the companies with him rushed forward and took their stand at the entrance of the city gate. The other two companies rushed against all who were in the fields and struck them down. 45And all that day Abimelech fought against the city until he had captured it and killed its people. Then he demolished the city and sowed it with salt.
