Judges 9:23-25

23And God sent an evil spirit between Abimelech and the men of Shechem; and the men of Shechem dealt treacherously with Abimelech:

24that the violence done to the threescore and ten sons of Jerubbaal might come, and that their blood might be laid upon Abimelech their brother, which slew them, and upon the men of Shechem, which strengthened his hands to slay his brethren.

25And the men of Shechem set liers in wait for him on the tops of the mountains, and they robbed all that came along that way by them: and it was told Abimelech.
