God sent an evil spirit - He permitted jealousies to take place which produced factions; and these factions produced insurrections, civil contentions, and slaughter.

Then God sent an evil spirit between Abimelech and the men of Shechem,.... Permitted, yea, gave a commission to Satan, the evil spirit, to go among them, who stirred up suspicions, jealousies, hatred, and ill will to one another, and sowed the seeds of discord and contention among them; or God gave them up to their own hearts' lusts, to think ill of one another, grow jealous, and meditate revenge:

and the men of Shechem dealt treacherously with Abimelech; did not openly declare their minds, but secretly conspired against him, and privately consulted ways to find means to get rid of him, and shake off his government.

Then God sent an evil spirit between Abimelech and the citizens of Shechem, so that they became treacherous towards him. "An evil spirit" is not merely "an evil disposition," but an evil demon, which produced discord and strife, just as an evil spirit came upon Saul (1 Samuel 16:14-15; 1 Samuel 18:10); not Satan himself, but a supernatural spiritual power which was under his influence. This evil spirit God sent to punish the wickedness of Abimelech and the Shechemites. Elohim, not Jehovah, because the working of the divine justice is referred to here. "That the wickedness to the seventy sons of Jerubbaal might come, and their blood (the blood of these sons that had been shed), to lay it upon Abimelech. " "And their blood" is only a more precise definition of "the wickedness to the seventy sons;" and "to lay it" is an explanation of the expression "might come." The introduction of לשׂוּם, however, brings an anakolouthon into the construction, since the transitive שׂוּם presupposes Elohim as the subject and דּמם as the object, whereas the parallel חמס is the subject to the intransitive לבוא: that the wickedness might come, and that God might lay the blood not only upon Abimelech, the author of the crime, but also upon the lords of Shechem, who had strengthened his hands to slay his brethren; had supported him by money, that he might be able to hire worthless fellows to execute his crime (Judges 9:4, Judges 9:5).

Then God {h} sent an evil spirit between Abimelech and the men of Shechem; and the men of Shechem dealt treacherously with Abimelech:

(h) Because the people consented with the king in shedding innocent blood, therefore God destroys both one and the other.

9:23 God sent - God gave the devil commission to work upon their minds.

23. Then God sent an evil spirit between Abimelech and the men of Shechem-In the course of providence, jealousy, distrust, secret disaffection, and smothered rebellion appeared among his subjects disappointed and disgusted with his tyranny; and God permitted those disorders to punish the complicated crimes of the royal fratricide and idolatrous usurper.

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.
