Judges 9:30-33

30When Zebul the ruler of the city heard the words of Gaal the son of Ebed, his anger burned.

31He sent messengers to Abimelech secretly, saying, “Behold, Gaal the son of Ebed and his relatives have come to Shechem; and they are stirring up the city against you.

32Now then, get up during the night, you and the people who are with you, and set up an ambush in the field.

33Then in the morning, at sunrise, you will get up early and rush upon and attack the city; and when Gaal and the people who are with him come out against you, you shall do to them whatever you can.”
