Judges 9:42-45

42The next day when the people of Shechem went into the countryside, this was reported to Abimelech.

43He took the troops, divided them into three companies, and waited in ambush in the countryside. He looked, and the people were coming out of the city, so he arose against them and struck them down.

44Then Abimelech and the units that were with him rushed forward and took their stand at the entrance of the city gate. The other two units rushed against all who were in the countryside and struck them down.

45So Abimelech fought against the city that entire day, captured it, and killed the people who were in it. Then he tore down the city and sowed it with salt.
