22 So Abimelech was chief over Israel for three years. 23 And God sent an evil spirit between Abimelech and the townsmen of Shechem; and the townsmen of Shechem were false to Abimelech; 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. 25 And the townsmen of Shechem put secret watchers on the tops of the mountains, and they made attacks on all who went by on the road and took their goods; and word of this came to Abimelech. 26 Then Gaal, the son of Ebed, came with his brothers, and went over to Shechem; and the men of Shechem put their faith in him. 27 And they went out into their fields and got in the fruit of their vines, and when the grapes had been crushed, they made a holy feast and went into the house of their god, and over their food and drink they were cursing Abimelech. 28 And Gaal, the son of Ebed, said, Who is Abimelech and who is Shechem, that we are to be his servants? Is it not right for the son of Jerubbaal and Zebul his captain to be servants to the men of Hamor, the father of Shechem? But why are we to be his servants? 29 If only I had authority over this people! I would put Abimelech out of the way, and I would say to Abimelech, Make your army strong, and come out.

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.
