Judges 9:30-33

30When Zebul, the city commissioner, heard the words of Gaal son of Ebed, he was furious.

31He sent messengers to Abimelech, who was in Arumah, reporting, “Beware! Gaal son of Ebed and his brothers are coming to Shechem and inciting the city to rebel against you.

32Now, come up at night with your men and set an ambush in the field outside the city.

33In the morning at sunrise quickly attack the city. When he and his men come out to fight you, do what you can to him.”
