Abimelech lived at Arumah: and Zebul drove out Gaal and his brothers, that they should not dwell in Shechem.
The citizens of Shechem, believing that the insurrection was over, were apparently in their fields for the purpose of tending their crops, and very probably without weapons of any kind.  Abimelech's brutal slaughter of those helpless peoples was part and parcel of his brutality toward his half-brothers in Ophrah.  The Sacred Scriptures leave no doubt of the diabolical wickedness of this evil offspring of Gideon's concubine.  He was one of the most detestable creatures who ever disgraced the earth.
