24 So that punishment for the violent attack made on the seventy sons of Jerubbaal, and for their blood, might come on Abimelech, their brother, who put them to death, and on the townsmen of Shechem who gave him their help in putting his brothers to death.
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.
