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.

Jud 9:22-49. Gaal's Conspiracy.

22. When Abimelech had reigned three years—His reign did not, probably at first, extend beyond Shechem; but by stealthy and progressive encroachments he subjected some of the neighboring towns to his sway. None could "reign" in Israel, except by rebellious usurpation; and hence the reign of Abimelech is expressed in the original by a word signifying "despotism," not that which describes the mild and divinely authorized rule of the judge.
