Judges 9:30-33

Zebul, governor of the city, heard what Gaal son of Ebed was saying and got angry. Secretly he sent messengers to Abimelech with the message, “Gaal son of Ebed and his relatives have come to Shechem and are stirring up trouble against you. Here’s what you do: Tonight bring your troops and wait in ambush in the field. In the morning, as soon as the sun breaks, get moving and charge the city. Gaal and his troops will come out to you, and you’ll know what to do next.”
