Judges 9:28

24 in order that the crime against the seventy sons of Jerubbaal might come to justice and their blood be avenged on their brother Abimelech and on the leaders of Shechem, who had helped him murder his brothers.

25 The leaders of Shechem set up an ambush against Abimelech on the hilltops, and they robbed all who passed by them on the road. So this was reported to Abimelech.

26 Meanwhile, Gaal son of Ebed came with his brothers and crossed into Shechem, and the leaders of Shechem put their confidence in him.

27 And after they had gone out into the fields, gathered grapes from their vineyards, and trodden them, they held a festival and went into the house of their god; and as they ate and drank, they cursed Abimelech.

28 Then Gaal son of Ebed said, “Who is Abimelech, and who is Shechem, that we should serve him? Is he not the son of Jerubbaal, and is not Zebul his officer? You are to serve the men of Hamor, the father of Shechem. Why should we serve Abimelech?

29 If only this people were under my authority, I would remove Abimelech; I would say to him, ‘Muster your army and come out!’”

30 When Zebul the governor of the city heard the words of Gaal son of Ebed, he burned with anger.

31 So he covertly sent messengers to Abimelech to say, “Look, Gaal son of Ebed and his brothers have come to Shechem and are stirring up the city against you.

32 Now then, tonight you and the people with you are to come and lie in wait in the fields.
