24 that the violence done to the seventy sons of Jerubba'al might come and their blood be laid upon Abim'elech their brother, who slew them, and upon the men of Shechem, who strengthened his hands to slay his brothers.

Matthew Henry's Commentary on Judges 9:24

Commentary on Judges 9:22-29

(Read Judges 9:22-29)

Abimelech is seated in the throne his father refused. But how long does this glory last? Stay but three years, and see the bramble withered and burned. The prosperity of the wicked is short and fickle. The Shechemites are plagued by no other hand than Abimelech's. They raised him unjustly to the throne; they first feel the weight of his sceptre.
