Judges 9:30-33

30When Zebul the governor of the city heard what Gaal son of Ebed said, he was very angry.

31Under cover he sent messengers to Abimelek, saying, “Gaal son of Ebed and his clan have come to Shechem and are stirring up the city against you.

32Now then, during the night you and your men should come and lie in wait in the fields.

33In the morning at sunrise, advance against the city. When Gaal and his men come out against you, seize the opportunity to attack them.”
