that the violence done to the seventy sons of Jerubbaal might come, and that their blood might be laid on Abimelech their brother, who killed them, and on the men of Shechem, who strengthened his hands to kill his brothers.
The "evil spirit" that God sent between Abimelech and the men of Shechem (Judges 9:24) was a spirit of discontent that proved to be disastrous. Judges 9:25 probably means that the men of Shechem conspired to rob Abimelech of the tolls he received from the travelers and traders who passed through Shechem. They did this by ambushing them from Mt. Gerizim and Mt. Ebal, the two mountains between which the road passed near Shechem. [Note: Cundall and Morris, pp. 130-31.]
