Judges 9:24 Meaning and Commentary

Judges 9:24

That the cruelty done to the seventy sons of Jerubbaal might
come
That vengeance might come on the authors of it; so things were ordered in Providence that this might come to pass:

and their blood be laid upon Abimelech their brother, which slew them;
be charged to his account, and he suffer for shedding it:

and upon the men of Shechem which aided him in killing of his brethren;
by giving him money to hire men to go with him to do it, and perhaps by words encouraging the assassins, and who might be of the city of Shechem.
